I feel we have two types of student, regardless of profession, those who want to learn to fly and those who want to be taught to fly. The learn to fly group will try and meet you half way if not more.The others I am sure do not think about flying when they are not in the aeroplane. My "best" student was a plant operator who was a dream student, my second best was a doctor, so go figure. There have been many other well and less qualified people who have been good students. It is really up to the individual and the effort they put in at home and in the aircraft. I think that consistency pays big dividends for the student.
