2. Live, breathe and inhabit the worlds you write about and your characters.
3. Never, ever think that anything you write is ‘unreal’ – the truth is really stranger than fiction.
4. If you have a bad day when nothing seems to be going right, get up the following morning and continue.
5. Above all, once you start, DO NOT STOP until you reach the end.
