If you suddenly decide, for example, in the middle of a distracted afternoon spent Web browsing, to switch your attention to a cognitively demanding task, you’ll draw heavily from your finite willpower to wrest your attention away from the online shininess. Such attempts will therefore frequently fail. On the other hand, if you deployed smart routines and rituals—perhaps a set time and quiet location used for your deep tasks each afternoon—you’d require much less willpower to start and keep going. In the long run, you’d therefore succeed with these deep efforts far more often.
