A very successful orchestra arranger from Los Angeles was asked how he got to be in the top of his profession. He said he wasn't the most talented or creative but when he put himself in positions of being asked to do a task he always rose to the challenge. In the process, he became very, very good at what he loves to do. His first step was to improve his education to the point that he could fake-it-till-he-made-it. Then he took the action step of moving to L.A. Then he networked with the people who could give him a break. Then he blew his own horn and let everyone know what it was he wanted. He got it. You can, too, by selling your books to non-bookstore buyers.
