There's always something impressive when people are giving themselves to their job absolutely. The military thing - I was conscious that their routine, their way of living is so opposite to mine. In some ways their life seemed intolerable to me. But, mine would be to them, too, because this strangely laissez-faire life of mine actually comes with its obligations as well.

For so long I didn't have any kind of readership at all - I'd get published, but not read - the idea of writing for an audience is so anathema to me, it's never bothered me.

These days any self-respecting exhibition of nude photos has to have pornographically explicit images to prove that they are works of art.

Have more than one idea on the go at any one time. If it's a choice between writing a book and doing nothing I will always choose the latter. It's only if I have an idea for two books that I choose one rather than the other. I ­always have to feel that I'm bunking off from something.

Beware of clichés. Not just the ­clichés that Martin Amis is at war with. There are clichés of response as well as expression. There are clichés of observation and of thought - even of conception. Many novels, even quite a few adequately written ones, are ­clichés of form which conform to clichés of expectation.

If Donald Trump thinks that just by being unpredictable that somehow he can have an impact, but not necessarily commit himself to certain things, that's not the way it is going to be read in foreign capitals. Foreign governments are going to take these things very literally and very directly.

In foreign countries, when people see what Donald Trump is saying on Twitter since the election and seeing what he's saying in these calls with foreign leaders, they take everything very seriously and they take everything very literally.
