I put "love," though probably it wouldn't be defined as such by most. In part, it's a love for my friends and others close to me, why I do things I do. But partly, it's more abstract.... something akin to what my dad said should be one's primary motivation in life, to leave the world better than you came into it somehow. So perhaps love for the world, particularly in my case for the outcasted and disadvantaged, would be the best way to describe it.
