I am a sleeper. When you wake up at 4:30 in the morning to do a workout, you're sleepy at 8 in the evening. By 10 o'clock at the latest, I'm in bed.

We learned about gratitude and humility - that so many people had a hand in our success, from the teachers who inspired us to the janitors who kept our school clean... and we were taught to value everyone's contribution and treat everyone with respect.

You should never doubt yourself.
