People are chasing cash, not happiness. When you chase money, you're going to lose. You're just going to. Even if you get the money, you're not going to be happy.

Well, I needed the work - that's the honest answer. I haven't worked for a while, a couple of years. So I thought it would be nice to get back to work and earn some money.

I want to sit with 80- and 90-year-old people more than anyone. They have played this game before. Not one of them has told me, 'I wish I had more money.'

I remember thinking that I'd way rather give my parents my money, and not have to like have them go to work anymore, you know what I mean. Because I'd way rather spend more time with them.

It's lovely to have money to give away - that's the bonus of winning the Nobel.
