I enjoy what I do and those whom I work with, and I feel I'm accomplishing good things for the world as well as myself in so doing.
If you have a truly important and rewarding job, e.g. performing life saving surgery on small children or cute puppies, and really enjoy it, then fine, keep working.
But most of us work the 98% of jobs that are NOT especially important and are not rewarding in any way other than salary and benefits. We work not because we wake up every morning thinking "Oh BOY! I can't wait to fight the traffic, get to my job, and spend 10-hours hunched over a computer churning out the financials on the Jones Account today!"
Sometime next week while you are at your job, ask yourself, "If I could be anywhere or doing anything right now, is sitting here at my job where I would choose to be if 1) I was not being paid to do it and 2) society/family didn't expect it of you?
If you can truly say that, compensation and societal pressure aside, there is nothing in the world you'd rather be doing than whatever you do at work, you are blessed far beyond what most people can ever hope for. Either that, or you need counseling for workaholism.
I hear people say "I love my job and wouldn't quit yada yada yada" all the time. But they usually change their tune pretty quick when I get them to really consider if that is what they really want to do, more than anything else in life.
When they really analyze it, the reason most of them work is to make money (with societal pressure being a distant, but significant, second). But if you already have more money than you need, why do something that isn't really what you most want to do, just to earn more money that you don't need?
BTW, it is NOT always easy to break out of the mold that society expects us to conform to- especially in the USA, where "work" is revered to an insane degree (far more than in Europe).
My wife is a perfect example. She says she likes her work, but bitches about it all the time.
But she simply can't pull the trigger and quit. She doesn't have the courage to put up with the crap she'd get from friends, family, society. So she trudges to work every day to make more money that we don't need.
I'm still working on her- if I can get a workaholic like her to quit before age 60, I'll consider it a victory. :)
