Creativity thrives best when constrained.

This is one of my favorites. People think of creativity as this sort of unbridled thing, but engineers thrive on constraints. They love to think their way out of that little box: 'We know you said it was impossible, but we're going to do this, this, and that to get us there.'

I really wanted to be a doctor, until my freshman year of college when I realized that while I was good at chemistry and biology, I really wasn't feeling challenged by it.

Your rhythm is what matters to you so much that when you miss it you're resentful of your work...So find your rhythm, understand what makes you resentful, and protect it.

If you push through that feeling of being scared, that feeling of taking risk, really amazing things can happen.

To me, speed is really about convenience.

I pace myself by taking a week-long vacation every four months.
