I Need a Job
Have you noticed how some characters come with their own jobs, and some need to find one? Some of them, like Sherlock Holmes, even invent their own jobs. There was no such thing as a “consulting detective” until Holmes became one. The job is the character, and the character is the job.
Or, to put it another way, sometimes the type of story you want to tell dictates what kind of job your protagonist needs.
And, sometimes, the type of job your character has dictates the story you’re going to tell about them. There are quite a few jobs that can bring a story with them, at least if you’re a genre writer. Detective. Queen. Knight. Wizard. Thief. Soldier. Then there are those whose story potential doesn’t seem quite so obvious. Servant. Miller. Potter. Cook. Farmer.
