  • - Make sure that you spend time on things

  • that give you a lot of return.

  • Don't spend time on things that give you little return.

  • Picking up a new skill can change your life totally.

  • If you just try and improve your life by 1% every day,

  • the effect over many years is extreme, is massive.

  • Every day, try and just learn something new.

  • That you're not too young,

  • you're not too old, to do something.

  • (soft upbeat music)

  • Before we even get started,

  • I wanna emphasize that you need to believe in yourself.

  • You need to believe that you can change your life in 2023.

  • You need to believe that you have the ability

  • and the capability to do this.

  • You need to ignore the haters.

  • You need to ignore the people that have told you,

  • at school or at other times in your life,

  • that you can't do it.

  • You need to get your mind in the right place

  • and believe in yourself.

  • And I'm telling you, you can.

  • If I can do it, you can do it.

  • I can't tell you the number of people

  • that have told me during my life,

  • or over the years of my life that, "David you're an idiot.

  • "David, you can't do it.

  • "David, I'm putting you into this box.

  • "This is the kinda person that you are.

  • "You can't be this person.

  • "You can't be a YouTuber because you're too old.

  • "You can't be an instructor

  • "because you're not intelligent enough.

  • "You don't speak with the right accent,

  • "you don't have the right education,"

  • et cetera, et cetera, et cetera.

  • Ignore those haters. Ignore those people.

  • Go out there and make the most of your life.

  • What are you gonna do in 2023 to change your life?

  • In this video, I wanna talk about the five top skills

  • that you need to get in 2023 if you haven't already.

  • It's really important that you ride the waves.

  • I've said this many, many times

  • and I've done this many, many times in my life.

  • Look at what the hot trends are, jump on those waves,

  • and ride them.

  • So I wanna talk about sort of five areas

  • that I really think you should look at

  • if you haven't already in 2023,

  • and then look at the skills that you need to get

  • to ride those waves.

  • You can't change the past, but you can change your future.

  • And for me,

  • that's what I love about technology or tech in general.

  • You don't need a fancy degree.

  • You don't need fancy contacts.

  • You don't need to be part of a old boys club, as an example,

  • to get somewhere in technology.

  • If you put in the effort,

  • in a few years you can change your life

  • because technology is changing all the time.

  • Look at me.

  • I got my CCIE maybe 20 years ago.

  • What was really, really important 20 years ago

  • or 10 years ago or five years ago,

  • isn't really important necessarily in 2023.

  • The hot technologies of those days are perhaps gone.

  • Things are constantly evolving, constantly changing,

  • which can make it harder,

  • if you've been in tech for a long time,

  • to keep up.

  • But the great news for someone like you

  • who's perhaps starting out is that if you start today,

  • in two years time you could be an expert

  • in a specific sphere or niche if you like.

  • Think about the blockchain. Didn't exist a few years ago.

  • (screen clicks)

  • Think about machine learning, AI.

  • That is changing the world in the last few years.

  • 10 years ago, 20 years ago,

  • that wasn't really important

  • compared to how important it is in the next few years.

  • Jump on the waves, ride those waves, and change your life.

  • Now, I'm gonna continue talking about mindset a little bit

  • and giving you some advice from my experience

  • but if you don't wanna hear that, that's fine.

  • Use the timestamps below to jump ahead in the video.

  • It's important to remember that Rome wasn't built in a day.

  • When you're starting out,

  • it can be overwhelming

  • because there's so much information, so much to learn,

  • but I'm telling you now

  • you don't have to try and learn everything like that.

  • Firstly, that's impossible.

  • And secondly,

  • there's just too much to learn very, very quickly.

  • The more you learn,

  • the more you'll find it's easier to learn additional skills

  • or pick up additional skills, learn new technologies,

  • because a lot of it's interrelated.

  • As an example, I have a strong foundation in networking.

  • For me to move into another area isn't that difficult

  • because I've got a strong foundation in networking,

  • programming, et cetera.

  • It's much easier to pick up new technologies.

  • But I want you to remember that life is a journey

  • and your path may change over time.

  • You may be doing this today

  • but then tomorrow you do something totally different,

  • and there's nothing stopping you reinventing yourself.

  • You could be the expert in this area

  • and then tomorrow or in a few years time,

  • you're the expert in another area

  • because technologies change

  • and you have to change with the technologies.

  • If people tell you, "You must stay where you're at,"

  • they've either not been in tech long enough

  • or they've stagnated because stagnation is a terrible thing.

  • You've gotta keep on reinventing yourself.

  • You gotta keep on learning

  • and changing what you're doing.

  • If you told me five years ago

  • that I'd have a million subscribers on YouTube,

  • (crowd cheers)

  • I probably wouldn't have believed you.

  • You've gotta keep on improving what you're doing

  • and keep on learning.

  • So to help you with that,

  • I wanna talk about some principles.

  • First thing I really believe in is circle of control.

  • You may not be able to control what governments are doing

  • or what certain people in the world are doing.

  • I don't watch a lot of news

  • because it can be really depressing.

  • You can't change

  • what people on the other side of the world are doing.

  • As an example, I live in the UK.

  • I can't change what the US President is doing,

  • so I don't focus on that.

  • I focus on the stuff that I can control.

  • I can control my time.

  • If you've got a job

  • and you have to work a certain number of hours,

  • your boss could control that.

  • But you may have some flexibility there

  • to decide what you do with your time.

  • And after work, what are you doing with your time?

  • What are you doing with your time on weekends?

  • - Work your ass off. (relaxing upbeat music)

  • There is no magic pill.

  • It drives me crazy to go to the gym.

  • You read one hour a day.

  • I went and worked out five hours a day

  • and I was working on construction with 24 hours a day.

  • Organize your day.

  • Work hard.

  • - As an example for me,

  • and I'm not telling you that this is what you have to do,

  • I don't watch television

  • because it can be a huge time sink,

  • as in take a huge amount of time.

  • I'd rather use my time for other things.

  • You need to decide what's important for you

  • and prioritize what's important for you.

  • But the point is, is you can control your time.

  • You can decide where you spend your time.

  • So don't spend time on things that give you no return.

  • Rather spend time on things

  • that will give you a long return.

  • As an example,

  • I learnt about networking many, many years ago

  • and that's helped me over 20 years as an example.

  • The stuff that I learned 20 years ago

  • are still helping me today

  • because it's a foundation that I build upon.

  • Rather spend your time learning something

  • that can help you for the future.

  • Another important principle is the 80-20 rule,

  • also known as the Pareto principle,

  • 80% of consequences come from 20% of causes.

  • As an example, in business,

  • 20% of your customers give you 80% of your revenue.

  • If you make sure that you focus your time on the 20%,

  • you're gonna have a far greater return

  • than focusing your time on things less important.

  • As an example,

  • if you watch a television program,

  • just some kind of entertainment,

  • that could give you relaxation now

  • but what's the return on that?

  • What's the long-term return on that versus, for instance,

  • reading a book that changes your mindset

  • or watching a video that teaches you something

  • that could give you a return over your whole lifetime?

  • You could learn something about investing.

  • You could learn something about technology.

  • And that could give you return after return after return

  • after return throughout your entire life.

  • Make sure that you spend time on things

  • that give you a lot of return.

  • Don't spend time on things that give you little return.

  • Picking up a new skill can change your life totally.

  • As an example, learning a programming language like Python

  • can be used for years and years and years and years.

  • Once you learn how to code,

  • you might use Python for a while or for many years,

  • or you may move onto another programming language,

  • but you've got over that hurdle of learning

  • a programming language.

  • The return on that investment can be massive.

  • Learning Linux, as an example,

  • can give you a massive return over your lifetime.

  • Spend time on things that give you a big return.

  • Don't spend time on things that give you little return.

  • A book that I often recommend is "Atomic Habits."

  • James Clear in the book talks about the 1% principle,

  • if you like, or 1% rule,

  • that if you just try and improve your life by 1% every day,

  • the effect over many years is extreme, is massive.

  • Every day, spend a bit of time learning.

  • Try and learn something new every day.

  • And it's amazing how that exponentially grows your knowledge

  • and opens up opportunities for you.

  • I've picked up many skills over the years.

  • Some of them would be technical skills

  • like networking, programming.

  • Some of them would be business skills

  • or just other kinds of skills like how to use YouTube.

  • So I have YouTube skills, I have social media skills.

  • I keep on learning,

  • keep on trying to develop myself in multiple areas,

  • and that knowledge becomes exponential

  • and can really change things.

  • Another good book is "Deep Work."

  • Very difficult for some people,

  • but often you need to put away distractions.

  • Get rid of your phone, turn off your notifications,

  • stuff like that.

  • Put it away

  • and make sure that you spend time every day doing deep work.

  • In other words, hard study.

  • A term that could be used for me is a creator.

  • I'm a content creator.

  • Content doesn't get created by me checking emails

  • or by looking at the notifications on my phone.

  • I often turn off all notifications,

  • block myself out from the rest of the world,

  • and try and spend time creating content

  • where I'm not distracted.

  • I need to turn off notifications

  • because can you imagine me

  • trying to create a YouTube video like this

  • and then getting constant messages?

  • I need to turn off the notifications and the messages

  • so that I can create content.

  • Now, you may not be a content creator,

  • but how do you think

  • you're going to study something difficult

  • if you don't turn off the notifications

  • and spend time learning?

  • You've got to do some deep work.

  • Some books that I'd recommend that you look at is,

  • "The 4-Hour Work Week."

  • Some people don't like the title

  • but there are a lot of good principles in that book.

  • Think about principles like the 80-20 principle,

  • circle of control.

  • Think about "1%," "Deep Work,"

  • great books to look at

  • that can really change things in your life.

  • You need to make the effort, however,

  • in 2023 to do things differently

  • to what you did in the past.

  • As that saying goes,

  • "It's insanity to do the same thing over and over

  • "and expect a different result."

  • Make sure that you do something different today, tomorrow,

  • this year if you're not getting the results that you want.

  • Now, this year,

  • I'm doing it slightly differently to previous years.

  • I wanna talk about five core skills

  • that you need to learn in 2023,

  • if you don't have these skills already.

  • And as always, please put in the comments below

  • if you disagree with what I'm saying.

  • Now, before I talk about the top five skills,

  • I wanna talk about five paths.

  • There's a lot of overlap with the skills

  • that you would require for these different paths.

  • The first path, which I think is really hot at the moment

  • and something that I would probably start looking at

  • if I was just starting my journey today,

  • is data science, machine learning, or AI.

  • Just recently ChatGPT has really blown up,

  • lot of interest in this AI.

  • If you really wanna ride the next wave,

  • if you want to change your life,

  • I would seriously look at data science,

  • machine learning, AI.

  • It doesn't matter which other sphere you're interested in.

  • Perhaps you're interested in cybersecurity.

  • That's been a very hot niche in the last few years.

  • AI can put you in a different league to others.

  • If you understand machine learning,

  • if you understand data science,

  • it can change your whole life.

  • I would strongly suggest that

  • you concentrate on that in 2023.

  • And what I'm planning to do this year

  • is create a lot of videos around this topic.

  • This will change many, many industries.

  • It really has

  • and it's gonna continue to do that more and more and more.

  • The ChatGPT software is just one example of what's possible.

  • It's amazing what that AI can do.

  • In my previous video, I put it to the test in cybersecurity,

  • in programming, in networking,

  • and it was amazing what it can do.

  • Have a look at that video below if you're interested.

  • But AI is gonna change things.

  • Now, if that's not of interest to you,

  • have a look at dev or programming.

  • There is always gonna be a demand for developers

  • in the world.

  • Now, think about the devices

  • that most people have with them.

  • Could be an iPhone, could be an Android phone.

  • These devices run on software.

  • People don't use their phones necessarily

  • to make phone calls, they use them for the apps.

  • So if you're interested in getting into programming,

  • I would strongly look at app development,

  • specifically on iOS, specifically on Android.

  • Fantastic place to make a good career for yourself.

  • But perhaps you wanna write applications for Windows

  • or Mac or other platforms, but look at development.

  • I've interviewed Dr. Chuck multiple times.

  • Have a look at the videos below.

  • He gives you a free path to becoming a developer.

  • He'll teach you Python, he'll teach you C,

  • he'll teach you SQL.

  • He teaches you a whole bunch of skills that you would need

  • if you wanna become a developer.

  • Perhaps you can't pay for an expensive school,

  • you don't wanna go and do a computer science degree,

  • have a look at his free videos

  • which help you become a developer.

  • Again, very, very hot in recent times is cybersecurity.

  • There's a big need for security professionals.

  • Many, many more jobs on the blue team side

  • rather than the red team side.

  • Companies need to be secure.

  • There's always gonna be a need

  • for people interested in cybersecurity,

  • so that's a great place to look.

  • Cloud is huge.

  • Amazon, we've got Google, we've got Microsoft.

  • I would specifically look at Amazon

  • if you're not sure which of the three to look at.

  • But cloud is big, only getting bigger.

  • More and more companies are moving their servers

  • from on-premise to the cloud,

  • so have a look at the cloud.

  • Another hot one to look at is blockchain.

  • And I'm not talking about Bitcoin,

  • I'm not talking about cryptocurrencies.

  • Have a look at blockchain for smart contracts.

  • Now, you don't have to focus on just one of these.

  • You could, for instance, be interested in cybersecurity.

  • So perhaps looking at hacking the blockchain

  • or helping companies secure the blockchain.

  • Very good areas, but I wanted to give you some bonus areas.

  • Have a look at APIs.

  • They've become very hot in recent times.

  • Some people will say, "Well, APIs are part of programming,

  • "so if you're a programmer, you have to learn about APIs."

  • But I wanted to put this as a bonus

  • because APIs are also really important

  • with regards to cybersecurity.

  • If you wanna become an ethical hacker,

  • hacking APIs is a great place to start.

  • APIs are used a lot in networking as well these days,

  • so APIs are really important.

  • And let me talk about networking.

  • It's very sad for me to say this

  • but I don't think networking is a high growth industry

  • for the coming years.

  • - [Crowd] Aw!

  • - It's become very mature.

  • It's a great stable place to get a job

  • but it's not high growth.

  • So if you wanna ride the next wave or the future,

  • get into the hot stuff, then networking is foundational.

  • It's really important, used by many of these other trends,

  • but it isn't the hottest place to get a job.

  • If you wanna go for a hot trend,

  • have a look at data science or machine learning or AI.

  • Have a look at some of the other sort of spheres.

  • Networking, I would say is a stable industry

  • but not high growth.

  • Another bonus is IoT, Internet of things.

  • I mean, are you gonna become a developer

  • that writes code for IoT?

  • Perhaps you're gonna get into cybersecurity

  • and hack IoT devices.

  • These devices are just proliferating everywhere.

  • We have smart homes.

  • The lights that I'm using here are so-called smart lights.

  • Smart devices are taking over the world.

  • More and more devices, washing machines, toasters,

  • et cetera, et cetera, are becoming smart.

  • If you're into hacking, again, fantastic area to look at,

  • or perhaps coding.

  • So there are five paths that I would suggest you look at.

  • Now, let's talk about the five core skills

  • that you need to get.

  • Let's say you're interested in machine learning

  • or you're interested in cybersecurity,

  • any of these spheres,

  • one of the foundational skills that you need is Linux.

  • Now, I've been saying this for years.

  • Learn Linux.

  • Learn Linux.

  • Learn Linux.

  • And I'll still say it in 2023.

  • Learn Linux if you haven't learned it already.

  • The world runs on Linux.

  • If you're into hacking or cybersecurity,

  • think of Kali Linux, think of Parrot OS.

  • Just think of the tools that you need.

  • They run on Linux.

  • If you're into machine learning, AI, Linux, once again.

  • If you're into networking,

  • networking devices often run or have a basis on Linux.

  • Cloud runs on Linux.

  • I mean, I can just repeat myself over and over again.

  • You need to learn Linux.

  • This is a paradigm shift for a lot of people.

  • Don't be a consumer, be a creator.

  • When you learn to code, it changes everything

  • because you can create your own tools.

  • You're not limited by the tools available

  • that others have created.

  • Best programming language to probably start with is Python.

  • If you haven't got any coding experience, look at Python.

  • But very soon after that, look at Golang, look at Rust.

  • Rust is the language I would suggest you look at

  • if you're serious about becoming a developer or coder.

  • If you're in cybersecurity, if you're into machine learning,

  • Python is a great place to start.

  • Great place to, you know, learn.

  • It'll really help you in your career.

  • But also have a look at Golang,

  • have a look at Rust soon after you've learned Python.

  • Now, another foundational skill is networking.

  • Basically, the world runs on a network, the Internet.

  • Internet of things means networking.

  • Cybersecurity means that you have to understand networking.

  • You don't need to become a CCIE like me.

  • You don't have to become even CCNP,

  • if you're not interested in networking per se.

  • You're perhaps interested in something else

  • but you need to have an appreciation of networking.

  • You need to understand an IP address.

  • You need to understand port numbers.

  • Have a understanding of networking as a foundational skill.

  • Important in cybersecurity

  • just to understand what a port number is as an example,

  • or what an IP address is.

  • The cloud foundational skill, once again,

  • it's one of the hot training areas in the last few years,

  • becoming more and more mature.

  • You need to learn about the cloud.

  • In the old days,

  • we used to install applications on physical hardware,

  • now we put them in virtual machines.

  • And that gets me to the next topic, virtualization.

  • And that's changed now to Docker containers,

  • so containers have become really hot.

  • So have a look at virtualization.

  • Make sure you have an appreciation

  • or understanding of virtualization.

  • If you work in cybersecurity

  • you're gonna wanna run Kali Linux, as an example,

  • in a virtual machine.

  • You need to understand what a virtual machine is.

  • But you may wanna take it a step further

  • and put that in a container which is a lot more lightweight.

  • Make sure that you learn virtual machines,

  • Docker and Kubernetes.

  • Great foundational skills to learn in 2023

  • if you haven't learned them already.

  • Lot of repetition of previous years here

  • but this stuff is foundational, it's important.

  • Right at the top, Linux. Make sure you learn Linux.

  • Make sure you learn a programming language,

  • even if it's just Python.

  • Make sure that you understand core networking principles.

  • Make sure that you understand the cloud.

  • Make sure that you understand virtualization.

  • As a suggestion,

  • go and get the CompTIA certifications in these areas.

  • So as an example, get Linux Plus from CompTIA.

  • Get Network Plus for networking.

  • Get Cloud Plus for the cloud, et cetera.

  • There are a bunch of introductory certifications

  • that you can get.

  • For networking,

  • if you wanna focus on becoming a network engineer,

  • CCNA is still my recommendation.

  • But if you wanna do cybersecurity,

  • you may not be as focused on networking

  • so Network Plus is fine for that.

  • Moral of the story is:

  • Read books, go on YouTube.

  • There are many, many places where you can get free content

  • to learn these skills.

  • You don't have to pay a lot of money to learn the stuff.

  • Okay, but what are you gonna do in 2023?

  • Are you gonna put the effort in?

  • Are you gonna put the time in and learn this stuff

  • and change your life in tech?

  • The responsibility is on you.

  • You need to decide what you're going to do.

  • I'm going to continue learning.

  • I'm not gonna stop learning.

  • You can't stop learning if you wanna be in tech.

  • You have to keep on learning.

  • And for me personally,

  • areas that I'm gonna really focus on in 2023 is AI

  • and development.

  • I wanna get back to the old,

  • old days of me doing development.

  • I also want to expand on the cybersecurity content,

  • but specifically AI.

  • (soft upbeat music)

  • I wanna put AI into different spheres.

  • AI in cybersecurity, AI in programming, AI in many places.

  • Big focus for me this year.

  • As always, I wanna wish you all the very best in 2023.

  • Go out there and make a success of your life.

  • (soft upbeat music continues)

- Make sure that you spend time on things
