At almost 40, I've come to realize that work gives me plenty enough opportunities to track and measure performance as it is. But there's also that part of life that's not work, and I've found that merely being, as opposed to performing, is quite valuable in itself! It's hard to enjoy the moment with my kids, my spouse and my friends when I constantly think of my todos and objectives. I feel by now that the goal is to learn to balance between times of performance and times of non-performance, even multiple times a day.
