Absolutely, that is the one reason that I would ever say to someone "don't be a teacher". Some people see teaching as all roses, they don't realize that there are a lot of thorns hiding in those roses. My first 5 years of teaching were made absolutely miserable by administration in my district, and I'm still trying to work out of that attitude (I'm in a new district now). I know that every job has it's bad parts, but teaching is an occupation that tends to be "romanticized" when it's really just another job. I love my students, I like most of the teachers I work with, I enjoy teaching, I just don't enjoy some of the other aspects. And I've come to understand that it's okay to not be the perfect teacher who loves her job 24/7, that I can have days where I absolutely hate it and still come back the next day and work through it. Such is life, right?
