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.

You have to adopt a mindset that says, 'Okay, in three months, I'll need to know all this stuff, and then in six months there's going to be a whole other set of things to know - again in a year, in five years.' The tools will change, the knowledge will change, the worries will change.

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

If you start your own thing, you can learn a lot really fast from doing things wrong.

We've had customers from the beginning. The reason people use Dropbox is because they really love it. We think more about who is going to be competing with what we are going to be doing, not with where we started.

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

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.
