Fortunately, you live in the culture capital of the galaxy. If you can't find something to do in Gotham, there is a real problem. Go to the Met, or MOMA, or the Frick, or the Whitney--or all of them. Go to the opera or symphony or a play or two or the ballet. Check out some jazz or whatever genre you dig. Go on an architecture tour. Go to a sporting event. Start walking or running or cycling. Join a reading group... Paint or blow glass.

You get the idea. There is probably more to do in New York City than anywhere else on earth (forgetting about the outdoors, like climbing and stuff). Dive in. Make yourself do stuff. Make yourself get out of the house. Force yourself to. P_eople in little towns across the US would kill for the opportunities you have. Take advantage of that. That's what I have done and it has largely worked.
