We have more and more ways to communicate, as Thoreau noted, but less and less to say.

The more ways we have to connect, the more many of us seem desperate to unplug.

For more and more of us, home has really less to do with a piece of soil than, you could say, with a piece of soul. If somebody suddenly asks me, 'Where's your home?' I think about my sweetheart or my closest friends or the songs that travel with me wherever I happen to be.

Where you come from now is much less important than where you're going. More and more of us are rooted in the future or the present tense as much as in the past. And home, we know, is not just the place where you happen to be born. It's the place where you become yourself.

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.

We readily go to the health club when our doctor suggests we need more exercise, but we regularly neglect the 'mental health club' that our well-being more truly requires.
