I've learned first hand that you can choose either end of the anonymous v. warmth spectrum, find somewhere in between, or waver between them. There's a coldness to people here (and anywhere) if you're looking for it, or a warmth if you're willing to try a little harder. Either way is fine, but I've talked a lot less about leaving New York now that I'm further on the warmer side of the equation. My happiness still ebbs and flows, so I don't think this has much to do with it, but I'm a little more comfortable with it and worry less about happiness itself, which tends to make me the slightest bit happier. Besides, a man much more eloquent and absurd than I once said, "You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life." (Camus)
Lesson #64: open yourself up a little and find the warmth in others, or at least recognize when you're ignoring it. Oh, and happy holidays :)
