You have to celebrate accomplishment though.Most people reject labels anyway because they can come across as pretentious... it's really others applying them. Unless they are the job description type label. Example. A renown artist may call himself a painter, or "just" a painter.
When you are writing stuff that nobody else wants to read... and when you keep at it and eventually you are writing stuff that you have people willing to pay money to read it. Thats such a huge milestone and it does deserve a label.
