I'm not a big note-taker, so I think that the way I decide is that whatever I remember I always consider something that's important. If I remember a joke then I know it's a good joke, if I remember a story then I know it's a good story, and so that's how I curate what stories I'm going to write for the book. And I go over them again, make sure there's a theme and all that stuff, but mostly, it is intuition.
