Though [Abraham Lincoln] never would travel to Europe, he went with Shakespeare's kings to Merry England; he went with Lord Byron poetry to Spain and Portugal. Literature allowed him to transcend his surroundings.

When I look at what a writer owes to the reader, it's critical to know that everything you're writing about is not made up in your head. I feel that unless you can document and be certain about what it is that you're writing about, the reader is going to lose faith in your own integrity.

I think the most important advice is, a person doesn't have to find out right away. It's not like their first attempt at finding a profession is the only one they're going to find. I might well have gone down other paths, and it still might have been okay. But if you find something that you love, and if it keeps deepening with each new experience, then just stay with it.

What I learned, more than anything, was that you can't have it all balanced perfectly at any one time. When I was young, it was much more balanced toward work. When I had my children, it was much more balanced toward love and family, and I didn't get a lot of work done. So you can't ask of it to be perfectly balanced at any time, but your hope is, before you die, you've somehow had each of those spheres come to life. That's probably more important than success in any one of those spheres alone.
