All understood that the energy required to make decisions is invaluable, and that that energy is best reserved for making decisions for bigger impact.
This is not just an idea or a way of thinking, either. It’s grounded in science, biology, physiology. The brain comprises around 2% of a human body mass, but uses about 20% of its energy. (This is not all because of thought, of course. That would be overly simplistic, and scientific studies vary.)
Nevertheless, making choices about the choices we make is one of the most powerful things we can do to preserve and boost our energy.
And boosting our energy in turn has a disproportionate positive effect on our wellbeing, productivity and happiness.
