I'm blessed by the fact I only need five hours of sleep on a daily basis. I do tend to regard Saturday and Sunday as work days.

You can only do three things with your money. You can spend it. You can invest it. Or you can give it away. And if you invest it, you're really just getting more money to give away or buy something. How many things can you buy? So I don't really think there's a lot of choices.

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

I regard food as fuel. I am not a brunch person.

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'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 am involved in a lot of nonprofits. And when I reached the ripe old age of 60, I wanted to provide leadership to some I had been involved in.
