Excerpts from this year's good commencement speeches

Here’s one of a number of choice “words of wisdom” compiled by The New York Times from various commencement speeches this year.

This one’s for the anti-multitaskers:

Samantha Power

National Security Council

Occidental College

You’ve got to be all in. This means leaving your technology behind occasionally and listening to a friend without half of your brain being preoccupied by its inner longing for the red light on the BlackBerry.

In many college classes, laptops depict split screens — notes from a class, and then a range of parallel stimulants: NBA playoff statistics on ESPN.com, a flight home on Expedia, a new flirtation on Facebook. I know how good you all are at multitasking. And I know of what I speak, because I, too, am a culprit. You have never seen a U.S. government official and new mother so dexterous in her ability simultaneously to BlackBerry and breastfeed.

But I promise you that over time this doesn’t cut it. Something or someone loses out. No more than a surgeon can operate while tweeting can you reach your potential with one ear in, one ear out. You actually have to reacquaint yourself with concentration. We all do. We should all become, as Henry James prescribed, a person “on whom nothing is lost.”
