I relate completely. My upbringing was not bad but it certainly wasn't good. I feel the same about the running group where I'm from. They are nothing like me. I am extremely disciplined, never skipping a beat, and I do it all alone. I spend A LOT of time alone, and I always have. I think that is what makes us who we are. We have spent so much time being alone and in introspective thought that we have become indifferent to the average man/woman. I love books about revolution, atrocity, philosophy, but it is very hard to find others interested in those topics. Most do not possess the ability or simply will never be interested enough to think on such a deep level.
I began to really notice my indifference when I went to college. I had spent 2 years working in the meat shop of a grocery store with hateful old men. I had also seen immense poverty, people who were holding on by a thread, doomed children, gangsters, elderly with no hope. At college everyone was so happy and carefree, a complete contrast to my environment at home. But when I was at college I had friends who had the same interests. My best friend on the XC team would love to listen to me ramble about whatever book I was reading or whatever idea or philosophy popped into my head while on a run. That always made me happy.
Now I continue to expand my knowledge and search deeper into peoples soul. I realize that I am destined to be a questioner, a born revolutionary. I watch peoples reaction, I take note of how they think, I ponder endlessly. I imagine you keep a close circle. Find those who value your intellect and in turn value theirs.
