I think one thing we talk about often is poverty, having money, and having a paycheque, etc., but as a former teacher and as a parent and coach of kids, I think there's something to be said that what's more important is the prosperity of a person. You see the smiles on people's faces after a hard day's work or after somebody, who hadn't been able to get a job before, finally gets one. That's the kind of stuff that probably makes you feel the most rewarded for what you're doing.
