The most important thing you need to do [in this job] is to have big chunks of time during the day when all you’re doing is thinking.

I actually think, when you're young, ambitions are somewhat common - you want to prove yourself. It may grow out of different life experiences. You may want to prove that you are worthy of the admiration of the demanding father. You may want to prove that you are worthy of the love of an absent father.

There are places I want to visit where if I'm wearing a baseball cap and some sunglasses I think I can get away with and mingle in a crowd.

If you only think about yourself - how much money can I make, what can I buy, how nice is my house, what kind of fancy car do I have? - over the long term, I think, you get bored. I think your life becomes diminished. The way to live a full life is to think: What can I do for others!

I think, as you get older, that's when your ambitions become "peculiar"...

I think a basic principle of our Constitution is nobody above the law
