Knowledge is the key that unlocks all the doors. You can be green-skinned with yellow polka dots and come from Mars, but if you have knowledge that people need, instead of beating you, they'll beat a path to your door.

You need an incredible amount of self-confidence to go digging around in someone's brain.

No matter how good you are at planning, the pressure never goes away. So I don't fight it. I feed off it. I turn pressure into motivation to do my best.

I would prefer to just continue to speak about truth and to speak about what makes sense.

One of the reasons surgeons have so much trouble separating Siamese twins is that nobody gets to do many of them. On the table, the anatomy is so different from normal, that you're constantly trying to figure out, 'Can I cut this? Does this wire lead to what?' It's like trying to defuse a bomb.

Even if you're Bill Gates, you've got problems. I'm sure he would probably easily give a few billion dollars to get rid of all the problems that he has.

Do not underestimate the importance of feeling special.
