When did you start writing novels? I'm 23 and I've had at least some interest in writing for most of my life. I've gone off and on it, throughout middle school it diminished a bit but I've always had his urge to write at the back of my mind. But being 23 now I'm a bit worried that I won't be successful as I don't have a job at the moment so people might just think I'm a loser who's freeloading through life.
Easy solution: get a job, and write the book. 99% of writers start off working a full-time job while they write after work/on the weekends. So do that. Problem solved.
