What do I include in a good autobiography?

I disagree a little with the above poster, focusing too much on just facts and favourites makes it seem a bit like you're just answering a chain letter survey about yourself. Besides, there's so much more to you than your favourite things! What are you really pionate about? What are some experiences that have shaped you as a person and helped you grow? What sets you apart from other people? Who do you care about? It's also good to put in a few good stories/anecdotes in an autobiography.
