I had too much of a burning desire to get into this sport to let some trivial thing like an arrogant instructor keep me from achieving my goal.
Thankfully, my instructor had me learn on a 6 foot span glider and I was on my own as soon as I could demonstrate basic control and the ability to land the stupid thing anywhere in the same time zone.
From there, I was given "mini lessons" with more advanced aircraft when the opportunity presented itself, but at least I was "checked off" to fly my big, lazy glider with just a bare minimum of "flight school" which was really a thrill at the time.
