Turning one's passion into a job almost always has this result. Work is never as exciting as doing something for the sake of doing it because work always has a finite list of things that must be done even if you don't want to. It doesn't matter if you're a programmer or a rock star. The routine of having to do something you don't want to do, whether that be write tests or perform the same hit song every day for 20 years, sucks. The trick is to try and find a balance. Do the boring stuff to pay the bills but find/make time to work on something that you actually enjoy. Sure it's not exactly easy to do but once you get out of school/your parents house - that's life.
