I had the day off today and there is snow on the ground and so I spent an extra long training session at the keyboard this morning. (44 minutes) Made it through the company-arranged session with five stars in three of the four categories. Still stuck on Target Tracker, which measures “attention.” After that, did some memory work and some work on Card Shark. Some progress in both areas. My big takeaway today is the reality of mental fatigue. Its no use continuing to do sets of push ups or pull ups one right after another in the hope of getting more reps the next time. The muscles get tired and you can actually do less and less. The progress – increased strength – shows up the next session – one or two days later – after your muscles have had time to replenish and grow. Hoping to see the same thing with this mental exercise, but still in the dark about how much is too much at one time.
No doubt, though. You do reach a point of fatigue and rapidly diminishing returns.
