I was tired. I hadn't slept eight hours in two, three years. I lived on four, five hours of sleep. You can do it during a campaign because thousands are screaming for you. You're getting adrenaline shots each day. Then the campaign ends, and there are no more shots.

One of the sharp parallels is that neither Vietnam nor Iraq was the slightest threat to America's national security.

I still love to go back to Mitchell [his home town] and wander up and down those streets. It just kind of reassures me again that there is a place that I know thoroughly, where the roots are deep. Everything had a place, a specific definition.

It can take greater courage to stand in opposition to the views of your neighbors or nation than to confront an enemy in combat.

I don't think the American people had a clear picture of either Nixon or me. I think they thought that Nixon was a strong, decisive, tough-minded guy and that I was an idealist and antiwar guy who might not attach enough significance to the security of the country. The truth is, I was the guy with the war record, and my opposition to Vietnam was because I was interested in the nation's well-being.

You never fully get over [losing a presidential campaign]. But I've had a good life. I've enjoyed myself 90 percent of the time.

Pay attention to the hungry, both in this country and around the world. Pay attention to the poor. Pay attention to our responsibilities for world peace. We are our brother's keeper.
