You are an author. Terrific!
Job or HobbyBut now the question is: Are you going to make money out of it or is it a fun sideline?
You can produce books as a fun and profitable sideline but don’t count on it. Writing takes work. It is a job. Writing books is not easy. Money from selling books is not easy.
HobbyIf you are writing books as a hobby, it means that you pay all the expenses and may be reimbursed some of the costs. Writing the book is not your day job.
