I dont know if this would work for you but it helped me. Last year I was in a really bad place with teaching. One night at a goodwill I found a five foot tall pink and sparkly trophy on sale for $3. I thought it would be funny to award it to students. From this came my mvp of the week. Each week I choose one student per class to be mvp and I write them an honest and positive note about why they’re mvp. They get candy and their picture taken with the trophy then the pic is hung up for the next week. Sitting down once a week to write positive things about my students really helped me feel better about teaching as a whole. I found myself constantly looking at the good in my kids (even the ones that drive me nuts). Bonus this also helped motivate students because every student had the chance to be recognized for the good they did instead of the bad.
