"Exactly - I mean, why be coached to fly an aircraft - we are all natural pilots anyhow."
Yes but one needs a license to fly an a/c properly. To change your personality you don't.
I knew of a psychopath who spent months getting coaching so as not to screw up the Psycho test. Well he passed to test but a leopard never changes it's spots, as 2 to 3 months later he exhibited every personally defect know to mankind.
