Flying is a fantastic leveller. If you can get hold of this months Flight Training News then read James McBrides article - someone of his level of experience is still finding new skills to aquire and new strings to his bow within aviation - and every time he goes into the classroom he admits it's as though he's back in short trousers!
Those quiet ones with the humble attitudes are usually the ones worth listening to but alas, in aviation as with any walk of life it's the stupid ones who have the loudest voices.
VFE.
