What made the Gary Paulsen want to write books?

Paulsen's realization that he would become a writer came suddenly when he was working as a satellite technician for an aerospace firm in California. One night he walked off the job, never to return. He spent the next year in Hollywood as a magazine proofreader, working on his own writing every night. Then he left California and drove to northern Minnesota where he rented a cabin on a lake; by the end of the winter, he had completed his first novel.
