“What you do is your legacy.”

“What you do is what matters, not what you think or say or plan.”

“If you are going to do something, do something that matters.”

“Once you [work on your idea extra hours], you'll learn whether your excitement and interest is real or just a passing phase.”

“Until you actually start making something, your brilliant idea is just that, an idea.”

“To do great work, you need to feel that you're making a difference. That you're putting a meaningful dent in the universe. That you are part of something important.”

“When you don’t know what you believe, everything becomes an argument. Everything is debatable. But when you stand for something, decisions are obvious.”
