Looking back, if I had to live my life over, there are things I would do differently, but the one thing I would not change is my charitable giving. I'm particularly thankful for my father's advice to set goals so high that they can't possibly be achieved during a lifetime and to give help where help is needed most. That inspiration keeps me energized and eager to keep working hard every day on giving back and making the world a better place for generations to come.

If you treat people with dignity, respect and friendliness, you can turn enemies into friends. An enemy is nothing but a friend in disguise.

If I had to predict, the way things are going, I'd say the chances are about 50-50 that humanity will be extinct or nearly extinct within 50 years. Weapons of mass destruction, disease, I mean this global warming is scaring the living daylights out of me.

I believe in a reasonable amount of "right to bear arms". But private citizens of the United States are not allowed to own nuclear weapons. I always wanted a nuclear weapon, if I could have gotten one. I'm every other kind of power, but I'm not a nuclear power.

I think Captain Cousteau might be the father of the environmental movement.

The Iranians don't intimidate! They're like the Vietnamese and the Iraqis. You want to start a war with them? They'll still be fighting in fifty years!

Once you decide to do something, and you're pretty sure you're right, then you gotta go ahead and do it. Because if you piddle around, somebody else will beat you to it.
