Derek Thompson defends vacations and workplace blog reading:

The bottom line is that breaks are better for our brains than overtime. Where you get your break — from an hour on blogs, a day in the park, or a week golfing at Martha's Vineyard — doesn't matter so much as that you get it. If you care about your own productivity, don't be afraid to goof off online. And if you care about decision-making at the national level, tune out the critics and root for your president's golf game.
