The advice to every aspiring teacher is always the same: keep a journal and reflect, reflect, reflect. Always wanting to do my best, I started a teaching journal when I landed my first teaching job. Instead of focusing on the pros and cons of a particular lesson, though, my journaling turned into an outlet for job related emotions. Many days (and years...and actually, right this very minute), I was intent on quitting. Other days, I was determined to be the best teacher I could. Sometimes I felt happy, and a lot of the time I felt crushed. Sometimes long stretches would pass without me getting worked up about anything at all. I kept this journal for ten years.
If you are thinking of quitting your teaching job, you’re in good company. If you are thinking about becoming a teacher, you should definitely read this so that all hope is lost BEFORE you start teaching. This will allow you to start with low expectations so that things can only go up.
