The adege is the same anywhere, people that do, the high achievers, and people that do not, the majority. Only those that have run their own business for a long time, understand the constant drive, the constant hastle, the constant rollercoaster, that is being in business. Alan Sugar, alludes at times to this, but like X factor (we all wanna be famous - with zero talent in a lot of cases), people tune in to The Apprentice, and see the wide eyed and bushy tailed wanna be'es. Old eyes look on and say be careful what you wish for. You just might get it.
I think the aviation community (pilots) are the same. The ability levels, the commitments, the drive to learn and improve, is vastly varied. And like the business world, some succeed, and some fail, only the BIG difference is that you may well die in aviation failure.
Not all business people are bright - look at the boards of Royal Bank of Scotland, The Bank of Scotland, HSBC, do you want me to go on..........
