Unless meaning makes me happy, I don't see the reason to focus on it.

This discussion is rather circular, to be honest. Happiness, by my definition, is a state of having achieved a goal or goals. (I wrote this lengthy thing over ten years ago trying to put hard definitions on words like happiness/satisfaction/pleasure etc: http://www.karmatics.com/docs/dictionary.html )

Maybe you define happiness differently than me, but I have a hard time understanding how it can be considered "not worth chasing" by any definition that makes sense to me.
