Helen Dunmore: Don't worry about posterity – as Larkin (no sentimentalist) observed "What will survive of us is love".
Geoff Dyer: Don't be one of those writers who sentence themselves to a lifetime of sucking up to Nabokov.
Anne Enright: If you had a terminal disease would you finish this book? Why not? The thing that annoys this 10-weeks-to-live self is the thing that is wrong with the book. So change it. Stop arguing with yourself. Change it. See? Easy. And no one had to die.
Richard Ford: Try to think of others' good luck as encouragement to yourself.
Jonathan Franzen: It's doubtful that anyone with an internet connection at his workplace is writing good fiction.
Esther Freud: Trust your reader. Not everything needs to be explained.
PD James: Open your mind to new experiences, particularly to the study of other people. Nothing that happens to a writer – however happy, however tragic – is ever wasted.
AL Kennedy: Have humility. Older/more experienced/more convincing writers may offer rules and varieties of advice. Consider what they say. However, don't automatically give them charge of your brain, or anything else – they might be bitter, twisted, burned-out, manipulative, or just not very like you.
Michael Moorcock: I always advise people who want to write a fantasy or science fiction or romance to stop reading everything in those genres and start reading everything else from Bunyan to Byatt.
Hilary Mantel: First paragraphs can often be struck out. Are you performing a haka, or just shuffling your feet?
