Niven's Laws On Writing

Join some of the greatest writers and minds, including Larry Niven himself, as they talk about what it takes to write something great. 

Niven's Laws On Writing (from Wikipedia): 

1. Writers who write for other writers should write letters.
2. Never be embarrassed or ashamed about anything you choose to write. (Think of this before you send it to a market.)
3. Stories to end all stories on a given topic, don't.
4. It is a sin to waste the reader's time.
5. If you've nothing to say, say it any way you like. Stylistic innovations, contorted story lines or none, exotic or genderless pronouns, internal inconsistencies, the recipe for preparing your lover as a cannibal banquet: feel free. If what you have to say is important and/or difficult to follow, use the simplest language possible. If the reader doesn't get it, then let it not be your fault.
6. Everybody talks first draft.
