"Kids are the toughest audience, but also the most rewarding."

创新不是选择，而是生存的必需。

People can be really smart or have skills that are directly applicable, but if they don't really believe in it, then they are not going to really work hard.

When public speaking， pause frequently. Pause before you say something in a new way， pause after you have said something you believe is important， and pause as a relief to let listeners absorb details.

Every day is a new opportunity to change your life.
