Summary

What if the way you think is costing you everything? Your brain filters 11 million bits of information per second, but only 50 make it through to your conscious awareness. That tiny keyhole shapes your entire reality. And in the age of AI, if you don't learn to control it, someone else will. Emily McDonald (@emonthebrain) is one of the most followed neuroscientists in the world. She has a PhD in neuroscience, studies how the brain constructs reality, and teaches people how to rewire their brains to win. In this episode, she breaks down the science of how your brain filters opportunity, why discipline makes you more attractive, and why AI is quietly destroying your ability to think critically. You'll learn: Why your brain constructs your entire experience of reality and how to reprogram it Why complaining literally shrinks your prefrontal cortex and what to do instead Why discipline is nervous system regulation and makes you biologically more attractive The reticular activating system and how to prime your brain to filter for what you want Why work life balance is a scam and obsession is actually required for success How AI is cooking your brain by training dependence instead of intelligence Retrain your brain to find EVERY dollar in your business.

If you want to be balanced, then you're going to get balanced results.

0:02.3

That's just the truth.

0:03.3

And I think that work-life balance is kind of a scam, that's fascinating. So what do you do? When you are obsessed, when you are all in, your brain starts to filter your reality for more opportunities to get it done. You need that in order to get what you want. Today's guest is one of the most followed neuroscientists in the entire world, Emily McGaulnell. She's going to help you use neuroscience to rewire your brain to win, destroy the negative loops who get stuck in, and the things that sabotage you. There's a really cool study. They would put this one group of kittens in an environment with only horizontal black and white stripes, and they put different kittens with only vertical black and white stripes. And then at the end of that, they put them into a normal environment with everyday objects. They would bump into them. They didn't perceive them the same way that a kitten that was raised to see vertical stripes did. Our brain constructs our entire experience of reality. Just like the table legs, a lot of the things that we want are actually right in front of our faces, but we can't experience them if our brain isn't wired for them. If people use AI frequently now, are we seeing anything in brain science about that having a negative effect?

1:00.0

It trains dependence, not intelligence.

1:03.0

A practice that I have in my life that is extremely helpful is...

1:07.0

Let's talk about attractiveness. You had this one video that I thought was so interesting.

1:15.4

And it was about that actually discipline can make you more attractive and the science has data to back that up.

1:22.7

There are studies that straight up show that traits like self-control and reliability and the

1:30.6

ability to follow through on your word.

1:33.0

Those are all traits that are seen as more attractive by the opposite sex, which are

1:37.2

kind of obvious, right?

1:38.2

Like yes, when I'm looking at even a friend or a romantic partner, yeah, reliability is something that I value in someone.

1:46.5

When we think about discipline, we think about forcing things and forcing yourself to do things.

1:51.9

For me, I've never thought of discipline that way.

1:54.0

I remember when I was in my PhD and my friend, we were at the grocery store and she has a mad

1:58.3

sweet tooth, and she'd be like, I'm like, I just don't get how you're so disciplined when it comes to your nutrition and for me it's never been about controlling

2:05.1

myself it's about looking out for future emily like what would future emily appreciate me do right

2:09.3

now because nutrition plays a huge role in how i feel biologically discipline is nervous system

2:14.7

regulation how would you feel in a room full of people that don't follow

2:18.8

through on their word are not trustworthy or not, you cannot rely on them, your head is going to be

2:23.3

on a swivel because you don't really feel safe in that environment versus if you were in a room
