Airprox,
Yes, I agree an instructor has the ability to instruct anybody. Doesn't mean that you can actually 'relate' to them. When I was 18, I didn't have a clue about anything, [or so I felt at the time] Unsure how I passed my basic training.... But Nowerdays, I seea more confident 'youth'. It is this youth that I take my hat off to, and acknowledge the generation gap.
Regardless, [although I acknowledge your comments], I still believe that life's experiences are those which enrich our capabilities.
Being a military QFI, thankfully [for my personality type], I became a QFI after 11 years of flying, but became an A2 about a a year later. Even now after 20 years of flying, I am glad that I really didn't instruct much earlier.
As my initial post suggested, opinions will vary in this regard.
Take and filter all the advise you receive.
Good luck....
