Do you ever want to give up?

Recently I have had a number of people comment on how easy my job is with all the holidays I get. They act as if it is the easiest job in the world and teachers are in it for an easy ride. Clearly they have never known a teacher very well. Not only do I find myself working hard to get students to take learning seriously but I also feel that I'm constantly defending myself to prove that I'm a professional and worthy of respect. I'm not sure if I have the energy to put this amount of effort in for much longer.
