You have to know why you get up every morning.

You rarely get satisfaction sitting in an easy chair. If you work in a garden on the other hand, and it yields beautiful tomatoes, that's a good feeling.

I have always followed exactly what interests me and never really worried about the money. And when you think about it, to be able to travel the world... on an expense account and do exactly what interests you, it just doesn't get much better than that.

You have to have a dream so you can get up in the morning.

We often think about happiness as trying to increase our joy, but it's also about decreasing our worry. So what you get for paying those high taxes is, if you're a parent thinking about putting your child through school, you don't have to worry about it, because all education through college is free.

The luster of an experience can actually go up with time. So, learning to play a new instrument, learning a new language - those sorts of things will pay dividends for years or decades to come.
