The only way to learn on a zero dollar budget is to talk to people

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.

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.

You need that hunger no matter what, because eventually the honeymoon period wears off. Somewhere between printing your business cards that say 'founder' on them and everything else you have to do, you realize, 'Oh, actually this is a ton of work.'

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.

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

You must maximize the probability that someone shows up at front door of your store or website and ends up with a solved problem.
