One of the most amazing men I ever met, a dear friend of mine, works for much much less money than his degree would allow him, giving up several benefits of living conditions, only because he's doing what he wanted - helping people who don't have money for a fancy private sessions (he's therapist).
The point is, he's one of the happiest men I ever knew, too. He's happy doing so much good for others and his family not only supports him on that, but loves him because of it even more.
Money = good thing, just not everything.
Carreer = has ups and downs any time.
Doing something you like and that makes you happy and content with your life = you can't buy it.

That wqas MHO and the proverbial 2 cents. :-)
