A zillion years ago, when I first began my teaching career, I wanted to be a great teacher. In fact, I wanted to be the best teacher ever. When my kids failed, I took it as a personal failure. Instead of blaming them, I blamed myself. I was depressed. I sat with my students. I asked them what I could have done differently to help them succeed. Mostly, I let them know that I really cared.
The majority of the students surprisingly never blamed me for their lack of success. I was always much harder on myself than they were on me.
As much as I wish I achieved my goal, I don't think I have. I'm an okay teacher, not terrible but there is nothing about me that makes me even near the best. In my old age, I've come to terms with that. I don't have the quietest classrooms in the school, I'm not as organized as I would like to be and I am definitely not nearly as smart as I am perceived to be.
I suppose it is okay to just be okay.
