Energy Spenders v. Energy Minimizers
This framework comes from a mentor of sorts to me, who I’ll call “John”, who drew on an idea from Robert Sapolsky’s Behave. Sapolsky’s insight is biological and deceptively simple: Humans evolved as energy conservation machines. For most of history, unnecessary energy expenditure meant death. Conserving energy meant survival. Over time, this imperative shaped our biases, habits, shortcuts, and prejudices. This idea shows how easily a biological truth turns into a practical life filter. John views people as sitting on a spectrum between energy spenders and energy minimizers. It is not good versus bad. It is descriptive. Most people never realize which one they are.
Energy spenders respond to ideas with curiosity rather than calculation. They lean toward complexity. They say “that’s interesting” more often than “that sounds like a lot of work.” They act before optimizing. From the outside, they often look chaotic, impatient, or inefficient. John described a Ukrainian employee of his who fit this archetype perfectly. He was not the most educated person in the room, but he was constantly moving, connecting, pushing, introducing, trying. That motion created optionality. Most of his efforts went nowhere. One or two changed everything. Energy spenders create upside because they are willing to expend effort without guaranteed payoff.
Energy minimizers, by contrast, instinctively calculate effort versus reward before engaging. They ask whether something is worth it before they explore it. They optimize for certainty and resist ambiguity. They are often highly intelligent, well educated, and perfectly logical. John described a Turkish engineer he worked with who embodied this mindset. Brilliant, rational, and thoughtful, but every idea passed through a filter of probability of success, personal reward, and effort required. Energy minimizers protect downside extremely well. What they rarely create is nonlinear upside. This is where the framework becomes uncomfortable. Intelligence ≠ outcomes. Education ≠ wealth. Rational optimization ≠ success. The world rewards motion, engagement, serendipity, and optionality. Those only emerge from energy spent without certainty. Energy minimizers avoid embarrassment, wasted effort, and failure. They also avoid the right tail.
This framework is useful because it applies everywhere. John hires for curiosity under ambiguity. He backs founders who are doing too much rather than too little. In his personal life, he believes engagement extends life and retirement accelerates decay. Energy use is not just economic. It is existential. I have found the same pattern in my own experience. In business school, among bankers, consultants, and many modern professionals, the dominant trait was extreme energy minimization. High IQ, perfectly logical, deeply optimized. Yet the people I have met who have achieved the most, whether in investing, sports or science, were energy spenders. They looked inefficient to the crowd. They failed loudly. They chased dead ends. They cared little about social standing or outside perception. And one success dominated everything else. The question I now ask is no longer who is smartest or most rational, but who is willing to spend energy before the outcome is known.
