"You should take a break — really. The best stretch of concentrated work time for your brain is 75 to 90 minutes, according to MIT senior lecturer and author Robert Pozen. And then you should step away, he notes: “When people do a task and then take a break for 15 minutes they help their brain consolidate information and retain it better,” he tells Fast Company. Even shorter periods of work time can still benefit from taking breaks — but make sure you’re using it wisely. The goal is disengaging from work thoughts, whether through meditation, talking to a friend, exercising, or even taking a nap."

Turn off your phone (or turn it to mute, if you can) and observe the world. Your next great idea might come to you.
