Cry me a river honduma$$, I poured basements for a long time till I wrecked my back. Two surgeries later I said I'm gonna learn to fly. I worked line service for three years at the local FBO getting my ratings , living off poor wages and left over catering. But I didn't ***** and moan about it . Geeze man if you don't want to be a CFI than don't be a CFI, no rule says you have to . just don't be an *********, cause it WILL come back to haunt you.
