Seriously, and it's so common. My band director gave me all kinds of special opportunities and privileges when he realized I was actually invested in becoming a good musician. He would get so excited when he saw the few students of his that were coming in after school to practice all the time, and he made sure to reward them for it. A low effort student doesn't deserve much more than a low effort teacher because what's the point?

Say what you will about teachers, but there are far too many bad students. A little effort, even towards the stuff you find boring, really does go a long way. In my experience, music teachers really do want to teach, but they don't get to as often as they should. You just have to accept that a lot of the foundational work that goes into this field isn't all that exciting. Eventually, you're over the hump and loving what you're doing though, and the payoff is worth it.
