One thing I've noticed about these quandaries: there's very little consideration for what one owes their society. Doing something in service to others may not bring an immediate 'happiness' but if you're looking for satisfaction in life, it's worth including in the balance equation.

And perhaps that's what the work you're doing can provide, if viewed from that perspective. Too many people seem to just automatically view work as soulless BS, to which I might suggest those people are simply in the wrong career.
