Actually it isn't. There's no other job that matches it. I think about all those bored secretaries in the offices I go to, and I know that most of them are staring at their watches and saying "god its only 2 o'clock" where I'm always finding myself saying, okay, its 2 o'clock, there's so much more time, plenty of chances to make more $. Its the only job I've had where I don't want the day to end. And there is a lot more skill involved than you might think. Not only with the riding, but with the ability to get in and out of buildings quickly, working your way through problems, and getting routes right. Its both mentally and physically demanding. I sure as hell don't do it because it pays extremely well, instead I think I do it because its an incredible job after you add up all the good and the bad.
