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.

The perfect life, the perfect lie, I realised after Christmas, is one which prevents you from doing that which you would ideally have done (painted, say, or written unpublishable poetry) but which, in fact, you have no wish to do.

Nicholson Baker talks about the way in which the most successful nonfiction books are those that can be boiled down into an argument so that everybody can wade in with an opinion without having to undergo the inconvenience of having to read the book itself. The more you can condense it, the better.

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.

It's "about" Stalingrad. Or, here's a book by Claire Tomalin: it's "about" Charles Dickens.
