Maintaining (fixing and updating) legacy code and be every bit as challenging and rewarding as building from scratch. You can learn a lot of skills that will also help you when you are building new code. Code reading and the art and discipline of minimal change while improving clarity are always useful if applied to legacy code or new code. Look into various books and articles on refactoring. Don't change things open-loop, write tests if you can, manually run and verify too.
