White collar jobs aren't all that flash either.
Regardless of what you're doing, the routine wears thin after a few years. Sure the bucks might be good and you might have a flash car, but do you sell your life & soul for the dollar ?
Joining the rat race down the freeway every morning and afternoon, getting to the same office, to do the same routine day in day out. Anything from 10 to 18 hour days - 5 on 2 off, sometimes 6/1. That's the reality of any white collar job that pays anything half decent these days. If you boil it down to an hourly rate the fact is your average mid to upper office jock really isn't on that good a wicket.
A mate of mine is 33 and had a successful non av career he'd built up over the years, pulling somewhere between 80 - 100k. He's chucked it in to get his CPL. Everyone is saying he's a crazy ****** but he says he's got an itch he has to scratch. I say good luck to him for having the balls.
