Purpose?

I'm not sure what my purpose in life is. That bothers me a little bit, but not a lot. What I do know is what everyone else's purpose in life is. That purpose is to make a difference to or for someone else. Whether its providing someone with the motivation to change themselves, inadvertantly setting up roadblocks on the highway of life, or just recognizing the same random songs as someone else to let them know they're not the only nutjob on the planet, everyone else is placed on this world for the sole purpose of having an effect on someone else...

...which in turn, explains my reason for being here. That helps me sleep a bit easier at night.
