I sometimes think that so much of our life takes place inside our heads, in memory or imagination or interpretation or speculation, that if I really want to change my life I might best begin by changing my mind.
    Wherever we are, any time of night or day, our bosses, junk-mailers, our parents can get to us. Sociologists have actually found that in recent years Americans are working fewer hours than 50 years ago, but we feel as if we’re working more.
    We have more and more time-saving devices, but sometimes, it seems, less and less time. We can more and more easily make contact with people on the furthest corners of the planet, but sometimes in that process we lose contact with ourselves.
    And one of my biggest surprises as a traveler has been to find that often it’s exactly the people who have most enabled us to get anywhere that are intent on going nowhere. That is, those beings who have created the technologies that override so many of the limits of old, are the ones wisest about the need for limits, even when it comes to technology.
    I once went to the Google headquarters and I saw all the things many of you have heard about: the indoor tree houses, the trampolines, workers at that time enjoying 20 percent of their paid time free so that they could just let their imaginations go wandering. One Googler was telling me about the book that he was about to write on the inner search engine, and the ways in which science has shown that sitting still, or meditation, can lead not just to better health or to clearer thinking, but even to emotional intelligence. The one thing perhaps that technology hasn’t always given us is a sense of how to make the wisest use of technology.
    And I think many of us have the sensation that we’re standing about two inches away from a huge screen, and it’s noisy and it’s crowded and it’s changing with every second, and that screen is our lives. And it’s only by stepping back, and then further back, and holding still, that we can begin to see what the picture in the screen means and to catch the larger picture. And a few people do that for us by going nowhere.
    So, in an age of acceleration, nothing can be more exciting than going slow. And in an age of distraction, nothing is so luxurious as paying attention. And in an age of constant movement, nothing is so urgent as sitting still.
