Jocko Underground: The Cure To Self Doubt. Exercise, New Baby, and Jocko is the New Chuck Norris.

Some people will try and discourage you from having any self-doubt, like 'you gotta believe in yourself,' right? For me, self-doubt is not only okay but kind of good in a way.

Fear is like fire ... It can warm you, and it can cook your food, or it can burn your house down.

The natural mode of operating for your mind is to close. That's the natural mode of operating. Why? Because it's safer, because it's easier, because it's more comfortable. So, the minute you have to open your mind up to someone else's ideas, it's gonna get uncomfortable.

It's unnatural to keep your mind open. It's unnatural ... It's not the human mode of operating to open up to listen to what other people have to say.
