Yep that's my take on life. In the big scheme of things I'm going to effect so few people that there's not much point trying. Little cogs with built in redundancy is all most of us ever manage to be. The only reason I've ever come up with is doing it all so the next generation gets a step up the ladder in helping make there pointless life a little bit more bearable, and for what? So they can do the same for there kids. Do I think there's some ultimate goal? No.
On the other hand though there's plenty of those so called pleasures of the flesh to take your mind of your worries and feelings of worthlessness. Maybe it's best to look at it in two sections. Personal existence and social existence.
