When I started reading I had no notion of different “genres” among the stories I read. For many years my readings were limited by a) the books I had available at home and b) the books teachers required me to read.
My first experience creating characters was when I started playing role playing games around 20 years ago. At the time, I had no idea how to approach the process. Thankfully, role playing games help you in this regard by providing you with frames of reference or archetypes you can choose from, such as “wizard”, “professor”, or “metal head vampire”.
In his book On Writing—one of the best I’ve read on the subject—Stephen King argues that, “if you want to be a writer, you must do two things above all others: read a lot and write a lot.” With this, as with many of the other writing tips the native from Maine expounds on the aforementioned book, I agree.
