My work life is intense. But I love what I do.

I don't really try to get involved politically by giving money to politicians or by saying I'm a Democrat or Republican. Right now, I just view myself as an American.

I've given some money to the scholarships in the District of Columbia, to the best students in D.C... many of the students have written me letters telling me they could not have afforded to go to college without the scholarship and money I've given them.

I realised how rich I had become and I asked myself, 'Do I really want to be the richest person in the cemetery?

People used to think that private equity was basically just a compensation scheme, but it is much more about making companies more efficient.

For me, few things are more compelling than watching a great opera.

I give away about 50 percent of my income, so my, you know, desire to give back to the country is pretty strong and I intend to give away a lot more. I've signed the giving pledge with Warren Buffett and Bill Gates, and I intend to give away the bulk of my money.
