disagree... just like every other profession you either have it or you dont. i went from zero to CRJ-900 in 14 months. first day/first flight of IOE i heard the words "your leg your brief"... and you know what, it went fine because i have it. I'm quite good at what i do, but at the same time i deeply hold the belief that every day in the air is another opportunity to learn something new and grow as an aviator. i've been humbled and i have impressed and i've never even touched a 172.
