I would say that talent is how good you can be at something without having to try (i.e. without hard work), and that as such it is a continuous quantity rather than a binary one. When talent runs out, the only way to get better is through hard work. In a way, I think being too talented at something is a handicap because you never learn how to work hard, and so you are unable to progress any further than your talent will take you.
