I usually think of the phrase self fulfillment more than happiness, though who knows what any of those words really mean. Seems rather out of fashion to discuss happiness as a goal. To me, happiness connotes a shallower kind of thing, like something that could be met by pleasures of the moment (a nice piece of chocolate cake, a shopping spree, a mindless, tipsy gathering). That's just the first thing that comes to my mind, not the only things I think people mean by the word happiness.

To me, self fulfillment connotes stuff like being able to acknowledge and live with the realities of the pain in the world (half the population that lives on less than $2/day, child abuse, war, injustice, etc.) and yet still keep a sense of meaning, purpose, and, at times, pleasure and happiness. I don't really think it's possible to entirely honestly face those realities all the time, but I guess a goal is being able to acknowledge them more and more honestly. By "acknowledging" them honestly, I mean probably feeling motivated and capable enough to do something about them...
