High school Teacher

Hello everyone.

I am a high school graduate of 2019 and I have been ambushed with the overwhelming question of what my purpose is. I really like helping people, I enjoy teaching and have a passion for history. I’m aiming for high school history, but I can’t help but wonder if there’s anything I should know before I head in that direction. Is anyone a education student and have anything to say on the courses? Anyone already a high school teacher and have an input?
