Questions on what I do, what it’s called?

Writer, author, novelist, reporter,..

Because of my health, I can’t do what I want, so looking for jobs is harder than I thought.  While laughing off my sadness, I thought : “Maybe I should create my own job or design my own new type of function.”

That got me thinking about my story and what functions there are in it. Does the name always tell what kind of a job it is or not? 
Maybe a herbalist could become a flora-hunter or something.
What is the weirdest most imaginative job function you can find?
