Ah, the afternoon slump—that inevitable post-lunch lull when the brain fog sets in and the end of the day can’t come soon enough. Thankfully, business school professor Christopher Barnes offers a solution for how to resist checking Facebook for the umpteenth time and, instead, making this part of your day more productive. For starters, don’t fight the slump by attempting to plow away at your work, says Barnes. Instead, use your slump time to return calls, emails or take care of any ‘busy work’ on your list that doesn’t require intense mental fortitude. Since this means you might have to readjust your to-do list order (the majority of us begin our days with emails and phone calls, which is a no-no), start with your most creative and focused work, says Barnes.
