19 y.o.'s make crap instructors anyway - they've got no maturity, no people skills, no interesting stories to tell and no real grasp of how to adapt the lesson to the student, i.e. they're f***ed the first time they run up against a student who doesn't "get it" the way they were taught to do it parrot fashion on the c cat course.
Throw in a shiny pair of raybans and a fake breitling, a desperate unconcealed desire to be out of the c152 and in the airlines, and the basic cluelessness about life that is the hallmark of most teenage school leavers from wealthy backgrounds, and you end up with something that actually costs the flying club more students than it brings in.
My advice - finish your CPL, go to London for a couple years, get drunk and see the world, save some money and come home via a long detour through Africa and west Oz looking for flying work on the way home.
