I used to work in the legal profession that gave me no sense of internal reward. I felt "stuck" at the time though, and it took me years to garner the courage to take a radically different path in my life. Now I'm in the healthcare field, after having worked for years to get a doctorate degree, and I feel like my "powers" are better used for good at this point.
What I learned was that money is vastly overrated as one quickly becomes accustomed to whatever income is earned such that that is "normal." I took risks and made a progressive decision to pursue a career in physical therapy though, which still has a nice salary while being a very internally rewarding profession.
