I play an instrument like you (except a different one from the ones you play) and there's a lot of pressure on me to be really good. My lessons teacher set goals for me to work toward that I have to have down by the time of a certain audition. I'm working really hard to meet them and improve, but I'm just not improving. My teacher told me to do a couple exercises on my instrument that she GUARANTEED would get me to my goals if I did them religiously but I've been doing them and I'm still not improving. I'm VERY worried I won't be ready by the time of the audition, which would be really embarrassing because a lot of people think I'm really really good even though I'm not. I really need some advice. Sorry, I don't mean to just dump my problems on you, but it seems like you've been through something similar to this... maybe?
i've never done music in that context
