The biggest pitfall to avoid is not writing. Not writing is really, really easy to do, especially if you're a young writer. The hope that elves will come in the night and finish it for you, is a very common one to have. That is my main recommendation - you have to write, and you have to finish what you write and beyond that, it's all detail.
Neil GaimanSometimes human beings are very much like bees. Bees are fiercely protective of their hive, provided you are outside it. Once youโre in, the workers sort of assume that it must have been cleared by management and take no notice; various freeloading insects have evolved a mellifluous existence because of this very fact. Humans act the same way.

Neil GaimanI don't think immediate tragedy is a very good source of art. It can be, but too often it's raw and painful and un-dealt-with. Sometimes art can be a really good escape from the intolerable, and a good place to go when things are bad, but that doesn't mean you have to write directly about the bad thing; sometimes you need to let time pass, and allow the thing that hurts to get covered with layers, and then you take it out, like a pearl, and you make art out of it.
