I remember reading a published article once about depression rates in adults, and its conclusions was there are significantly higher levels of depression and anxiety in individuals who took on intensive careers that they did not enjoy. The motives they had for taking on these careers wasn't given, but its questionable as to whether they took these jobs because they were well paid.
It really depends on what you want from life. Having a ludicrously well paid job is one thing, but you have to do it every day - and if you hate it or dont enjoy it, will you really be enjoying your life? Will you have much in common with your co workers who love the job?
Id rather wake up every day to a less well paid job, but actually wake up in the morning and think, hmm, todays going to be a good day, rather than waking up in a mansion and thinking, sigh, i have to go to work again.
Regardless, without sounding stereotypical, Ive been reading a few of your replies and it seems that you have been brought up in a cultural way that reflects your opinion. So I dont blame you for thinking the way you do.
