From what I've seen of management classes, and a number of professional managers...the paycheck is willing, but the mind is weak. ;p
Yup, its a generalisation. But after two years of useless management training in my degree, I have reason to be grumpy.
But I'd have to say one thing: I pity anyone who chooses an occupation based solely on an effort vs. paycheque philosophy. Do something that you enjoy - you'll probably be happier.
