If you want to be a writer, keep a notebook. You need to jot down every idea for a story that comes into your head. Don’t think to censor your ideas either! The idea is new and you are too close to it to judge its value. Ten years later it may strike you in a totally different way. I estimate that out of every thirty ideas I jotted down into my notebooks, twenty-nine proved to be worthless. The thirtieth had the potential to be developed into a novel or short story. The bad news was that quite often I found out that somebody had written something similar already!
