The happiest and most successful people I know don't just love what they do, they're obsessed with solving an important problem, something that matters to them.

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.

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.
