On writing his first Star Trek book: "People were worried that somehow, by writing this book I was going to give up that mystery of Garak, and Garak now was going to be completely understood, but I think just the opposite happened." You learn from your failures - at least I do. When things go right, you don't sit down and analyze them. But when something goes wrong, I sit and analyze and consider and get introspective. In personal life or professional, not succeeding teaches you more.
