One of my favorite lessons is best summed up in the words of an old Athabascan Indian who told me, “There are many hard things in life, but there is only one sad thing, and that is giving up.”

Whatever scares you, go do it.

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 mother said — and I didn’t realize how well it works — when I’d bring a drawing to her, she said, “I don’t look at the drawing. I looked at the child, and if the child was excited, I got excited.” And then we could discuss it. Because we were bringing something that meant something to me as a child. And so she would join in my lassitude, or my excitement, or my frustration. She wasn’t a psychologist, but she did understand this simple matter. Also, it accomplishes the only thing that has any meaning to a little child. The only thing an adult can give a child is time. That’s all, there isn’t anything else. That’s the only thing they need, really, is time. If you give them time, you’ll have to be understanding of them and give them time.

But I couldn’t let myself feel that way until it was all right to. And that’s part of the surgical mind too, addressing what you need to, and you know you can do, and postponing how you feel about it, thinking only of the patient and what you need to do.
