The mind is a terrible thing to waste

Nowadays there's a lot of tension building in the majority of the population. Maybe I'm the only one but I'm definitely sensing it in a lot of people. Probably a mixture of things. Today we remember 9/11, others hyped over the political race, and other might have that on top of their daily stresses. Something about the air though has got me distraught though. I'll start off by saying i'm not sad or depressed or anything along those lines but recently I've been feeling worthless. Not like the shameful kind of worthlessness that makes you feel down in the dumps but the insignificant feeling that can come with the feelings of worthlessness. The kind of insignificance that makes you wonder your part in the world. It's been a while since things got deep so why all of a sudden out of nowhere some mysterious force or entity or just pure chance has dropped an exponentially large load on my thought process.. I mean come on who does that? I've got such bigger fish to fry and worry about that than how I am feeling. I've got school, I've got the gym, I've got work, I've got family, I've got friends, and many other things crossing my mind before I start thinking about the world and my part in it. I understand all the theories about like the butterfly effect or if you went back in time just your presence being there would change everything thus making everyone and everything significant in the grand scheme of things, but are we?... Time doesn't stop for us, so as humans we just keep on moving. yeah of course we'll stop to mourn and stuff for example like today but for most of us that didn't directly lose someone on 9/11 do you stop on a daily basis to think about those that did die? A strong portion of people don't, but does that now make us insensitive? To only care about those that died on the anniversary of their departure? It is a different story for those that lose a loved one and for the most part(i guess) a lot of them would want you to look for love again and to not let your life get stagnant but is that right do with regard to time and our part in the world? And now that all that is said where do we fit in all this? where do i fit in general? How do i know I'm living my life right when most signs point to no. Do i stick with the logicality of it all or do I go with that gut feeling. the butterflies that tell you your doing a good thing or that wrench twisting when something doesn't feel right. Why are we getting all caught up in things that are irrelevant to happiness and why can't i get all this off my mind... I'm not supposed to be the thinking type. i'm just a laborer. A brother. A son. A friend... so why am I thinking all of a sudden?
