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 really hope that the philanthropy movement is seen not just as wealthy people giving money away but wealthy people giving away their time, their energy and their ideas.

I'm on a lot of nonprofit boards, but if I didn't enjoy it I wouldn't do it. I haven't yet done anything that's transformational in philanthropy. But I hope at some point to target two or three causes or organizations and really make transformational gifts.

Moneymaking was never anything to me. I was happy never making money; I just was happy doing things I liked. But I fell into the money thing. I now don't feel guilty about it, but I am determined to give away the bulk of it and enjoy doing it.

It's clear to me when you do private equity well, you're making companies more efficient and helping them grow and become more profitable. That success means our investors - such as public pension funds - benefit, which contributes to the economic wealth of society.

Persist - don't take no for an answer. If you're happy to sit at your desk and not take any risk, you'll be sitting at your desk for the next 20 years.

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.
