You don’t need to plan every minute of your day in advance—in fact, that would probably end up causing you a great deal more stress and worry than it would spark happiness—but you should try to get the most out of your workday so that you can relax and enjoy your time away from work. One of the best ways to be effective is to plan your day in intervals. For example, work for an hour, take a ten- minute break, work another hour, take a thirty-minute break, and so on. Because your brain cannot concentrate for longer than a few hours at a time, planning your day in intervals can improve your productivity.
