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.

You define a good flight by negatives: you didn't get hijacked, you didn't crash, you didn't throw up, you weren't late, you weren't nauseated by the food. So you are grateful.

The biggest surprise was that a country like Angola, that has so much money, that produces so much oil, would be in such a mess and so difficult to travel in. Something is almost cursed in striking oil. It's like the lottery winner who ends up broke.

When I'm writing, I like to travel alone. If you really want to find out about a place, you need to be as free as possible to be spontaneous. You also need to be lonely, because loneliness is a great teacher, too.

Travel books are all sorts - some are autobiographies, some are about falling in love. Some are about having great meals, some are about suffering. There are as many different kinds of travel books as there are novels. People think a travel book is one thing. It's many things.

Everyone had an opinion and no one had a solution.

Someone who seems doddery is perhaps not doddery at all but only an older person absorbed in squinting concentration, as though on an ultimate trip, memorizing a scene, grateful for being alive to see it.
