I’d compare college tuition to paying for a personal trainer at an athletic club. We professors play the roles of trainers, giving people access to the equipment (books, labs, our expertise) and after that, it is our job to be demanding.

I was hugely impressed... was the ultimate example of a man who knew what he didn't know, was perfectly willing to admit it, and didn't want to leave until he understood. That's heroic to me. I wish every grad student had that attitude.

It is not the things we do in life that we regret on our death bed. It is the things we do not.

When you see yourself doing something badly and nobody's bothering to tell you anymore, that's a very bad place to be. Your critics are the ones telling you they still love you and care.

It's not how hard you hit. It's how hard you get hit... and keep moving forward.

You can't control the cards you're dealt, just how you play the hand.

Put on your own oxygen mask before assisting others.
