Constant decision-making drains mental energy, gradually reducing clarity and judgment quality.

Top leaders achieve better outcomes by deliberately doing less and focusing on high-impact decisions.

Cutting decision load with routines, delegation, and defaults preserves mental energy for key choices.

Most advice for high achievers emphasizes doing more, moving faster, and juggling everything at once. But that approach quietly undermines what matters most: the quality of decisions. The issue isn’t effort—every choice, big or small, draws from the same finite mental energy. Over time, even the most capable people notice subtle shifts in clarity. This isn’t classic burnout—it’s a gradual erosion of sharp thinking.

To understand how top leaders manage this, I spoke with Jake Brydon, founder and CEO of Heritage Construction. Across multiple ventures, he noticed a consistent pattern: The strongest decision-makers weren’t doing more—they were deliberately doing less.

The Hidden Cost of Constant Decision-Making

Science may help explain why doing less can be more effective. For instance, a recent study reported that repeatedly choosing among multiple options drains mental resources, reducing capacity for self‑control and leading to declines in decision performance over time. Frequent successive decisions not only deplete mental resources but also weaken higher‑order thinking, making it harder to stay focused on long‑term priorities.

Neuroscience explains why. For instance, the prefrontal cortex, responsible for reasoning, planning, and impulse control, loses efficiency under sustained cognitive load. As mental energy depletes, even highly capable professionals make less precise judgments.

For leaders,........
