Decision fatigue

How many choices do we make every day? From what to wear or what to have for breakfast to the route to the office, all choices take energy.

Making decisions takes energy. Even when those decisions are small and everyday.

Decision fatigue is a real thing.

Being aware of decision fatigue is why tech company bosses such as Mark Zuckerberg and Steve Jobs made choices to stock their wardrobe with multiple versions of the same thing.

Jim Collins, in a recent podcast interview with Tim Ferriss, spoke about making one decision that rules out 100 other decisions down the line.

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.
