I do play tennis, but I don't really like competition. I'm supposed to be so intense, but I hate competition.

Real self-esteem has to be earned. I also believe in virtuous circles, like, nothing is fun until you are good at it. It is great if you can instill in children the ability to not give up, to have a work ethic.

I'm suggesting that, ironically, the secret to becoming a world 'hyperpower' is tolerance. If you look at history, you see great powers being very tolerant in their rise to global dominance.

Never complain or make excuses. If something seems unfair, just prove yourself by working twice as hard and being twice as good.

I'm a slave to my dogs and go out with them almost every day. They are poorly behaved if they don't run. They really act up.

You know, parenting is so personal. And we're all afraid that we didn't quite get it right. And it feels like the stakes are so high. By we - what if we made a mistake?

Most things are difficult at the beginning and they become fun, something you love, only after you've worked at them.
