How many of you out there are teachers?

I am thinking about going back to school (Im 31) to get my teaching degree. I have always wanted to be a history teacher. I have always loved history...especially Military History. I was wondering how hard it was to get your degree? Like I said in a previous post, I am planning on moving back to Tucson, and right now, I am a professional Bagpiper 7 days a week, I used to be in the family buisness (jewelry) but decided that 8.5 years working with family is about 8 years to much...anway. Just curious.
thanks,
Chad
