The human brain is an incredible pattern-matching machine.

I went to Princeton specifically to study physics.

If you build a great product or service, people will talk about it. But it starts with having something that's worth talking about.

When you are eighty years old, and in a quiet moment of reflection narrating for only yourself the most personal version of your life story, the telling that will be most compact and meaningful will be the series of choices you have made. In the end, we are our choices.

The thing about inventing is you have to be both stubborn and flexible. The hard part is figuring out when to be which.

If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

You don't choose your passions; your passions choose you.
