I've started taking Linear Algebra this quarter and am feeling very burnt out when it comes to math. Last quarter I was so interested in math that I founded the math club at school, but now I honestly don't give a **** anymore. Not getting along with certain teachers, especially the "faculty adviser" that was appointed to me for the math club really drained me. Linear Algebra should be simple, since I'm most comfortable with matrices and numbers, but I don't know. I don't care anymore. Is this common? How do you guys stay interested when outside factors take away from your interest/concentration/motivation?
