When I worked in the White House for President Carter, we tried to do comprehensive tax reform and we made some progress, and other presidents have as well.

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.

All I'm doing is I'm filling out my tax returns - or my accountants are, and I'm paying whatever I'm supposed to pay, though I'm giving away a large amount of the money and that probably lowers my tax rate because I'm giving away so much money. But change the law, but don't blame me for the law. I'm not writing the law. I didn't write the law.

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

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 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.

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.
