Purpose

I've been wrestling with the idea of "purpose" recently. More specifically ... what is my purpose? Not for a career ... but as a person taking up space on this planet. However complicated a question, it's beyond me to answer ... but are we all allotted some specific role/purpose to take on during our lifetimes to make living worthwhile? I'd like to say no because there are so many unhappy people in the world. Still ... the questions begs asking.
Or maybe I'm just confusing purpose with happiness. Right now I just feel like I'm going through the motions with no clear path, and little motivation to become more than I am. I feel deep inside that I'm capable of so much more ... yet where the hell do I start or where do I go? I'd like to think that one day it'll hit me in the face like a ton of bricks or an overly-ripe peach, but I've got the feeling those days are quickly going the way of the dodo. Either I've got to get the train going myself ... or if the train does arrive ... I've got to be ready to jump on.

I guess I've just got to wait this one out ... for now.
