Quit what you're doing professionally, go out and forge a path elsewhere. Maybe, not in the western world. Go to India, South Pacific, South America. Find a need there, and start filling that need & see what can come about from making a different kind of positive change in a persons life.

Maybe, it's digging a well. I don't know, but, what you're doing now doesn't seem like its gratifying for you. If all of that is a bit extreme, go help out at a homeless shelter, or food bank.
