One fourth of our population lives alone. While I believe introversion provides value to our daily lives, I can't help feel overwhelmed by this new trend. It is our inter-connectivity, our interactions, that provide meaning to life. I can hear a lot of people saying "... but Paul, life has always been about self-preservation". I don't have a reasonable argument against that, but we still look to others when we're at our greatest need. So then, without others, it's not much of a life.
Others reinforce our sense of purpose. Right now at the end of my second year, I'm struggling to find what mine is to be in the coming year. In other words, I'm looking for others.
