I have stayed with the same job for my entire adulthood (24 years now). It is a profession; it is what I love to do. I can imagine a 22 year old with high aspirations not wanting to "work" when he sees himself as a writer. But there is a reality that he needs to face. He needs a job and money to live, and until he has become that famous writer, that's probably what he's going to have to do. His ideas sound a bit manic. Is he being seen by a doctor who is monitoring his moods? Is he in therapy? Those are things that would be vitally important right now.
