There's no such thing as an aspiring writer. You either sit down and write or you don't. There are people who think about writing books and people who write books. If you want to write a book, the only way to do it is to write a book. There's no magic formula, no special club you have to join, no special process you have to follow. Get your butt in the chair, put your fingers on the keyboard and put one word after the other.
