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.

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.

If you have a dream, you can spend a lifetime studying, planning, and getting ready for it. What you should be doing is getting started.

You're not going to become a great manager overnight. You're not going to become a great public speaker or figure out how to raise money. These are the things you want to start the clock on as early as possible.

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.
