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

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.

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 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.

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

As the baby boomers like me are retiring and getting ready to retire, they will spend whatever it takes - and theyre the wealthiest generation in our country - to make themselves live an enjoyable life in their retirement years.

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