This is my third year and I am feeling rather down. While I feel like I am the best I've ever been at my job (I teach middle school language arts), I am just not seeing my purpose right now. Yeah, I feel like most students are learning and I have a lot of kids who have said I am their favorite teacher or what we did in class was fun, but I just can't see the impact I'm making in their lives as a whole. At what point did you realize that you really, truly, made their lives better? Or does that actually happen?
