Thank you everyone for the information. For the record I may have given a bad image of my past two instructors. In my opinion both have been great teachers, and I wouldn't trade my time with them for anyone else. They didn't just complain about their job unprovoked. I had to pull that out of them, both are far too professional to ever do that on their own. If flight instructing is the only available path then I will take that path, and be the best teacher I can be.
