Do you actually think $40K/year is a great salary? In Ohio?
To the OP: I teach in a Title 1 school, where we have all sorts of apathy and poverty. It can be depressing to have people tell you that you are not doing a good job when it is the kids who are actually not performing. I will say that despite this, I have not had a bad year of teaching in my almost finished career. It all comes down to your attitude. Do you want your job to suck, or do you want it to not suck. Your attitude will determine which of these occurs.
