When people tell me I can't do something, I have a visceral reflex to say, 'Yes, I can.'

I know a lot of CEOs who are looking for three- to four-year varsity athletes - not necessarily because these people are going to be doing pushups or spiking volleyballs in the workplace, but because they're looking for that continuity, that person who was gritty about something.

When people think of the word 'drive,' they often think you have it or you don't, and that's where we're wrong. Drive is something that can be encouraged by a wonderful teacher, by a terrific classroom environment, by an awesome soccer team that you are on, and it can be squashed as well.

Nobody gets to be good at something without effort, no matter what your aptitude is.

I'm so much more gratified by my life now that I have an expertise. I wake up every day thinking about a fairly small set of scientific questions all related to the psychology of achievement, and I'll never get bored of those questions. That's something I couldn't say to you when I was 22 or 25 or probably even 31.

You cannot will yourself to be interested in something you're not interested in. But you can actively discover and deepen your interest.
