Working on my novel, I was wondering what,exactly, my main character did. I knew that he had a love of three things: photography, movies and music. I knew outright that photography was only a hobby and he/I didn't know where to start with the movies. So, going with the Music bit, I made him a freelance DJ...I wanted to hit myself for thinking it. It was a good idea, and I might look into it when/if I do some tooling to the story. But it didn't go anywhere. So, I did the most sensible thing, or at the very least put in a plausible contingency plan: His mentor left him a mansion/inheritance that made him independantly wealthy
