Better to have your enemies inside your tent pissing out, then to have them outside your tent pissing in.

I think with Lyndon Johnson, the most important thing I learned was that he never had the sense of security that comes from inside. It always depended on other people making him feel good about himself, which meant that he was always beholden, continually needing to succeed. He could never stop. There was such a restlessness in him.

People will love him (Theodore Roosevelt) for the enemies he has made.

I keep thinking that history runs in cycles, and that some day certain large issues will come before the country again. There will be leaders that inspire young people. I don't think it means that it's over forever, but I'm getting pretty impatient. I'm hoping it comes soon, so that my young people can know that experience that we knew in the '60s, and that the World War II generation knew during the '40s.

Even though Lyndon Johnson's presidency was in many ways scarred forever by the war in Vietnam, and destroyed in a lot of ways, he - as a character - was even larger than his presidency. Being able to get to know him well, that firsthand relationship with this large character, I think is what drew me to writing books about presidents.

You can't start out at 20 in whatever your profession is and say, "I want to win an Olympic medal," or "I want to become president," or "I want to win the Pulitzer Prize." If you love what you're doing, it's sort of a nice thing that happens toward the end of your career, or in the middle of your career. It is not the reason you were doing it. The reason you were doing it is because every day you wake up in the morning and you can't wait to learn something new.

He (William Howard Taft) had little patience with the unconscious arrogance of conscious wealth and financial success.
