I’m no Buddhist monk, and I can’t say I’m in love with renunciation in itself, or traveling an hour or more to print out an article I’ve written, or missing out on the N.B.A. Finals. But at some point, I decided that, for me at least, happiness arose out of all I didn’t want or need, not all I did. And it seemed quite useful to take a clear, hard look at what really led to peace of mind or absorption (the closest I’ve come to understanding happiness). Not having a car gives me volumes not to think or worry about, and makes walks around the neighborhood a daily adventure. Lacking a cell phone and high-speed Internet, I have time to play ping-pong every evening, to write long letters to old friends and to go shopping for my sweetheart (or to track down old baubles for two kids who are now out in the world).
