Where you live matters: there’s only one MIT. And there's only one Hollywood and only one Silicon Valley. This isn't a coincidence: for whatever you're doing, there's usually only one place where the top people go. You should go there. Don’t settle for anywhere else. Meeting my heroes and learning from them gave me a huge advantage. Your heroes are part of your circle too - follow them.

The hardest-working people don't work hard because they're disciplined. They work hard because working on an exciting problem is fun.

One misconception is that entrepreneurs love risk. Actually, we all want things to go as we expect. What you need is a blind optimism and a tolerance for uncertainty.

You can’t focus on what everyone else is doing — it has to be about what’s really broken and what you can do to fix it.

There are 30,000 days in your life. When I was 24, I realized I’m almost 9,000 days down. There are no warm-ups, no practice rounds, no reset buttons. Your biggest risk isn’t failing, it’s getting too comfortable. Every day we’re writing a few more words of a story. I wanted my story to be an adventure and that’s made all the difference. Instead of trying to make your life perfect, give yourself the freedom to make it an adventure, and go ever upward.

Surrounding yourself with inspiring people is now just as important as being talented or working hard.

A lot of times it's an asset to not know everything about everything... A lot of really great, innovative things have happened when people just didn't know it wasn't supposed to be possible.
