Most time-strapped executives know they should plan ahead and prioritize, focus on the important as much as the urgent, invest in their health (including getting enough sleep), make time for family and relationships, and limit (even if they don’t entirely avoid) mindless escapism. But doing this is easier said than done, as we all know—and as I, too, have learned during years of trying unsuccessfully to boost my effectiveness.

In my case, I stumbled upon an ancient meditation technique that, to my surprise, improved my mind’s ability to better resist the typical temptations that get in the way of developing productive and healthy habits. Much in the same way that intense, focused physical activity serves to energize and revitalize the body during the rest of the day, meditation is for me—and for the many other people who use it—like a mental aerobic exercise that declutters and detoxifies the mind to enhance its metabolic activity.
