A young mechanic or even a football player is doing a job though, moon. He has to get stuck into the crap jobs to begin with to prove that he's hardworking and he'll be an asset to the business. Martial arts is different, you're paying for a service, being downtrodden isn't part of the deal. Besides, in martial arts you prove that you're hardworking by sticking at the training even if it gets hard, not by folding the black belts' gis and sweeping the sensei's yard. EDIT: I'm a poet and I didn't know it!
