Hello. It's a great honor to give this talk today.

How many of you would like to be successful in life?

Well actually, the two most important keys to success in life are:

Guess which one you can do the most about.

There are pills to cure just about everything,

but unfortunately, there are no pills to cure low levels of intelligence.

My talk is going to focus on self-control.

In the 1960s and 70s, a Stanford psychologist

developed an ingenious way to measure self-control in children.

He put a marshmallow in front of them, and told the kids,

but if you wait until I come back, you can have two marshmallows."

and then did follow-up tests on them decades later.

And what he found is that kids who waited for two marshmallows,

They had higher standardized test scores,

they were more likely to graduate from college,

The kids who ate one marshmallow immediately, they all went to jail.

the researchers found that the kids who waited for two marshmallows,

had more activity in the pre-frontal cortex.

in charge of, thinking, reasoning, and emotional control.

Psychologists call these 'executive functions.'

So poor self-control is actually responsible for many problems in life,

eating unhealthy food, not wanting to exercise,

addictions to the internet or alcohol, tobacco, just to name a few.

People also have trouble controlling their finances.

Some people spend more money than they make.

Some people have trouble controlling their sexual desires,

And this can lead to very difficult consequences.

And people also have trouble controlling their anger.

Indeed, anger is the emotion people have the most difficulty controlling.

And sometimes anger can even lead to criminal behavior.

For example, by far the greatest cause of murder is anger.

No other cause even comes close, like drugs, nothing even comes close.

two criminologists wrote a very influential book

What general factor could cause all crime?

No, actually, the best predictor of criminal behavior,

So, for over 25 years, I've spent my career studying human aggression.

And aggression often starts when self-control stops.

is tell you about a few studies that we've conducted

on the link between low self-control and aggression,

but before I do, I want to tell you a little bit more about the brain,

because, the brain plays such a critical role in self-control.

The human brain's about the size of a grapefruit.

And although it's only about two percent of our body weight,

it uses 20-30 percent of the calories we consume.

Calories provide fuel for the brain that it uses for many functions,

including those executive functions I talked about earlier:

thinking, reasoning, and emotional control.

people have the most difficulty controlling is anger.

I don't know if you've noticed this or not,

but sometimes when people don't get enough food to eat,

they have trouble controlling their anger.

Hungry people tend to be cranky, irritable, angry.

How many of you know what I'm talking about?
