I thought often during my years in the White House of an admonition that we received in our small school in Plains, Georgia, from a beloved teacher, Miss Julia Coleman. She often said: "We must adjust to changing times and still hold to unchanging principles."

My father said to me, “You need a piece of paper to go into a door sometimes.” I didn’t understand about résumés, but when you write a résumé you have to put down things that people want to know about.

My mother used to say to me a thing which, when I look back on it, wasn’t terribly logical. — and I had a pretty hearty appetite, but when I had had a large meal put in front of me, and even I couldn’t get through it, she would say, “Edmund, remember the starving millions in Asia.” Now what possible use my consuming it would do for the starving millions in Asia, I don’t really know, but the fact remains that I was brought up to think about the starving millions in Asia. That meant I had to clean my plate up and not waste it. Later on, I got more involved with the starving millions in Asia, perhaps in a slightly more practical way: helping some of them with schooling and hospitaling and even in agriculture.

Oh, my granddad was ahead of his time. He was always in favor of education. My dad and mother were too, but Granddad was very aggressive in that. You know, as he used to say, “You’ve got to fill your head with new ideas so you can use them later to improve your own status and that of the neighborhood.”

you have got to be totally honest and give advice and analysis that you’re asked to give that’s based on evidence. And if the analysis that you come to comes to a conclusion that a president might not like to hear that, you can’t be afraid of saying, “Mr. President, with all due respect, this is the way I think the situation is.”
