Reading is also a journey. It's a process of discovery.

Travel is about failure or overcoming obstacles, overcoming failures. When a traveler is having lots of good luck, that is not a happy book. That's a book you say, well, I don't need that. I want a life lesson. I want to find out - I want a journey that reflects my life.

Friendship is also about liking a person for their failings, their weakness. It's also about mutual help, not about exploitation.

Many aspects of the writing life have changed since I published my first book, in the 1960s. It is more corporate, more driven by profits and marketing, and generally less congenial - but my day is the same: get out of bed, procrastinate, sit down at my desk, try to write something.

If people are driving you around to look at animals, that's wonderful. That's educational, but it's not necessarily enlightening and you're not finding out much about yourself.

When you travel you realize how small you are. You need to be humble. You can't be a big, brash American. You think you have problems. You leave the States and you see people have bigger problems than you, much worse problems than you. They have nothing to eat, they have no water, they have no shelter, they have a terrible government. So you realize we complain about the government, we complain about food, whatever it is, and go somewhere else and you think, "Now I realize," you say, "Why people want to come to America."

You can't want to be a writer. You have to be one.
