- 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)
