I’m not kidding. From the Harvard Business Review:
Thanks to our smartphones, tablets, and laptops, it’s easy to be working all the time. But our devices can actually make us less productive by interfering with an important mental process: daydreaming. To be effective, our brains need opportunities to be “off,” which is hard when we’re constantly taking in new information through our devices. And research has found that letting our minds wander facilitates creativity and long-term thinking. If we’re facing a challenge that needs new ideas, we’re more likely to find some if our minds drift away from the problem for a while. So the next time your mind starts to wander, let it. Don’t check your favorite website or your email. Instead, walk to a window and think about the people and cars going by, close your eyes and notice the sounds around you, or go for a short walk. And remember: leave your device behind.
