I never imagined I'd write a book.

The value of experimentation is not the trying. It's the trying again after the experiment fails.

When my books came out, they started selling but they started selling at a relatively consistent but low pace. And they started to pick up the pace.

If you hire people just because they can do a job, they'll work for your money, but if they believe what you believe, they'll work for you with blood and sweat and tears.

Ideas are like dreams; they will disappear unless we record them. Write a book, a blog, build a company, anything that makes the ideas real.

I never set out to do the things I'm doing now.

Too many people write books because they want to be a New York Times best-seller. They want the glory and the fame.
