Models show that if 80% of people wear masks that are 60% effective—easily achievable with cloth—we can get to an effective Ro of less than 1. That's enough to halt the spread the disease [COVID-19].

As Tim Ferriss has said, 'I don't journal to be productive. I don't journal to find great ideas or put down prose I can publish later. The pages aren't intended for anyone but me. I'm just caging my monkey mind on paper so I can get on with my fucking day.'

We always lose when we lose our tempers. Something happened, and you got pissed. Now, two bad things have happened.

The better you get, the less you care. Whether it's a great athlete or a great comedian, the truth is the same: The better they get, the less they care about results. That's not to say they don't care about winning or about success; of course they do. It's that the longer you do something, the closer you get to mastery, the less external results matter in terms of measuring progress.

Reading, boxing, swimming, puzzles, coding, journaling, golfing—whatever it is, you need to have something that takes your mind off work. You can't be all about business.

My definition of success is autonomy. If you don't have control over your life day to day, you're not powerful or free.

The more you help your kids, the more you're hurting your kids ... If you do everything for your kids and you spoon-feed them, they're never going to know how to fend for themselves, and that's not going to be a good thing.

I'm living in a way I've never lived before. First of all, I'm truly grateful for every day, everything, but I'm only doing what I want to do, when I want to do, on my terms ... I will cut off relationships in a heartbeat with friends if they're an ass to me once. I don't care. I'm too good. I don't have time for this.

Getting angry rarely makes things better—even if it helps you get what you thought you wanted. It taxes your heart. It causes you to be mean to other people. To win, you had to lose your self-control.

You don't need more. You have enough. You can be happy right now.

According to a study conducted by the Harvard Business School, participants who journaled at the end of each day had a 25% increase in performance when compared to a control group that didn't.

The worst thing you can do—and this is from someone who is maybe a little bit of a workaholic—is wake up and check your phone. Honestly, if I can give one tip to anyone, it's don't even look at your phone.

Because we don't know what we want, we just want what other people want, and this locks us in this weird keeping up with the Joneses arms race competition to win contests that we, to use your word, don't actually give a fuck about.

And what I did was, I just sat there the entire time through the pain, and I would just imagine myself on a beach, doing my gymnastic rings, feeling healthy, feeling powerful, feeling completely cured. Everything was great. And you know what? ... I think, 4 or 5 months later, I was doing my gymnastic rings on a beach, watching the sunset, just enjoying it, feeling great...

There's a great Marcus Aurelius quote—he says 'We care about ourselves more than other people, but we care about other people's opinion more than our own.'

It's the inner game ... The inner game is the ultimate game. If your inner game's off, everything's off, because your inner game will get you through the good and the bad. And the inner game will make the bad bearable; it'll get you through it. But if the inner game is off... that's when it's really bad.

There's a Bertrand Russell quote... 'The first sign of an impending nervous collapse is the belief that your work is terribly, terribly important.'

Our job, whether we're surgeons or sailors, driving our kids to school, or driving in the Indy 500, is to be prepared for the things that life can throw at us. It's to think, in advance, about the potential problems and have solutions for them.

Imagine what it must have been like to be a gay person born in the 1950s when even an accusation was enough to wreck your career and carefully constructed life. Imagine how disorienting it would be if your gender was even a question you needed to consider for more than a second.

I remember thinking, I am a good man; I don't deserve to go like this. This is not how I deserve to go. And then I thought, oh, shit, I have no choice... I had to give in to that. And in that moment, I remember having to give in to that. I had no fucking choice.
