There was a Seinfeld episode in which Jerry’s dad was working at a job Jerry opposed. To get him fired, the plan was to schedule lots of late afternoon meetings, because the old man would naturally be tired by that time of day and look bad in front of the boss.
It was funny, but also true. What’s more, you don’t have to be “old” to find your energy lagging at certain times of the day.
Fortunately, there are some techniques that allow you to avoid mid-day tiredness, and even to find extra energy for the activities you’d like to pursue in your work and your life.
