I understand: You focus so you can finish. But focus is hard. We aren’t built for perpetual laser focus that blocks out the world and shines a spotlight on the one vexing problem we want go deep on for hours at a time. It’s physiological.
We’re built to make quick judgements and move on. Attention is expensive and in the world of our ancestors, it could cost dearly. It’s expensive in that your brain is the most energy-intensive organ in your body, consuming half of the sugar your body uses in a day. And not just any of the dozens of sugars our bodies use– only glucose, which it must pull from the bloodstream. Think a lot and your blood sugar drops.
