Think of happiness as the car you drive in, instead of a destination.
Can't really get anymore specific than that, because happiness is on the same level as taste. Just figure out what makes you happy, then do it on a daily basis.
Yes. I've come to the conclusion that it's not where the path takes you, but the path itself. Life is not about birth or death; life is about living. That being said, I operate entirely off goal and plans. So my path is typically a gradient of goal-points. Small victories, brief amusements. All in a direction I enjoy.
