On a different note to the previous posts........
I got involved in the instructing thing and at one stage starting leaning they way you feel now although for me it was when I first began.
The reasons I later found for it were that I was quite happy in the a/c or doing groundwork with the student but what was getting to to me was 1) Over doing it (working too longer days with nearly no days off) 2) Getting caught up in other peoples problems and other political B******T that can go on at times.
I found for myself that cutting back on the instructing and going out to work parttime (not in avaition) fixed this immensley by putting a different perspective on life. If you can do that with the organisation you with do it.
