Confused

Do you ever get in those ruts where nothing makes sense to you? Like, nothing at all, not what you plan to do in life, not what the rules are, and especially not why it's so hard to become a music teacher!
I love music. A lot. But it seems like you have to jump through 70 hoops at once to become a teacher. I learn things in some classes I know I'll never use. Some things just don't apply for a Band Room. And it seems like the things I really feel I need to learn, I'm not getting. I have no idea how to run after school programs, like Marching Band and Jazz Band, and Pep Band, but is there a course to take to learn that stuff? Nope. Just like there's nothing for Show choir for the vocal majors.
Sometimes it feels like I'm trapped in a major that I shouldn't be in. When I decided to be a music major, it was assumed that I was instrumental. In all actuality, I probably would have chosen vocal, had I known I had a choice in the matter. I'm definately not great at singing or at playing my euphonium, but it seems like I've always had more fun singing, and singing solos, than playing solos. I have such a hard time keeping time when there's no one conducting me. And in all reality, how many Band Teachers need to be able to play solos? I can understand the need to be able to play well in a group, which I'm good at, but solos are just a pain, and I'm sure all music majors agree with me there. If I wanted to play solos all the time, I would be a music performance major! Lol. Oh well. Complaining gets you no where.
