It sounds like you are not in love with helicopters and the people who want to learn to fly them. I am not an instructor, I am at soloing stage and would swap my highly paid, and fulfilling job, for that of a helicopter instructor. You make it all sound like a chore. Why did you learn to fly one of these incredible machines in the first place? The money? You were bored? What did you hope to get out of it? Surely the thrill of handling one of these engineering marvels and manipulating a mass of conflicting forces is sufficient thrill? Isnt it?
