Take a Break!
Mental work requires a great deal of energy. Just because the mental process isn’t as visible as it’s result doesn’t mean that it is any less taxing than a physical task. Our brains work just like every other organ in our body. Most of us cannot run at the same pace for more than an hour. Why do we think our teams can sustain mental ability longer than a marathon runner runs? A great book for any team to read is The Way We Are Working Isn’t Working by Tony Schwartz and Jean Gomes. It is a great book that advises us to take a 15 minute mental break every 90 minutes to help us pace our mind throughout the day.
