You’re most likely to take a loss after a big win.
It’s a phenomenon sports analysts strategy “hangover effect.” Teams that dominate one week often stumble the next. Boxers who demolish opponents sometimes get their world rocked the following fight. Stock traders who hit massive gains frequently throw them away in subsequent trades.
Success can make you complacent.
The company on top of the hill doesn’t maintain its rate of development. founder who raises a massive round of funding burns through it faster than peers on shoestring budgets. Students (like me, once) who learn they can ace tests without studying eventually bomb hard.
The psychology behind this is predictable. Victory breeds overconfidence. Success reduces vigilance. Winning feels like validation that you’ve cracked the code, that the hard work is over, that you can now coast on talent and the compounding returns of prior success.
This also plays out in more subtle ways. In the UK, over 60% of car accidents happen within five miles of the driver’s home. Not because the roads are dangerous, but because familiarity breeds carelessness. The route you’ve driven a thousand times is the one where you stop paying attention. Experience doesn’t always sharpen focus. Often, it dulls it.
In relationships, we see the same pattern. The couple who finally resolves a major conflict can neglect the smaller tensions building underneath. The friend who’s always been there becomes the one you stop making effort for. The job you fought hard to get becomes the one you sleepwalk through.
These are all micro-versions of the same trap: treating achievement as a resting point rather than a waystation.
Consider what happens in evolutionary biology. Species that perfectly adapt to a specific environment become incredibly vulnerable to change. The creatures that thrive long-term aren’t the most specialised. They’re the most adaptable. The ones that never stop treating survival as an ongoing challenge, not a problem they’ve solved.
The ancient Greeks understood this deeply. They had a word for it: hubris. Not just arrogance, but the specific blindness that comes from believing you’ve transcended the normal rules. Every Greek tragedy follows the same arc: a hero rises through skill and courage, then falls through the very confidence their success created.
In modern business, the pattern is almost mechanical. Kodak dominated photography so completely that they buried their own digital camera invention. Nokia held 40% of the mobile phone market and dismissed touchscreens as a gimmick. Blackberry’s executives literally laughed when they saw the iPhone.
Each of these companies didn’t fail because they lacked talent or resources. They failed because winning had made them deaf to signals that contradicted their worldview. The same intelligence that built their empires became the filter that prevented them from seeing what was coming.
What’s particularly insidious about this pattern is that it feels like wisdom. The person coasting after success isn’t lazy, they’re “strategic.” The company ignoring market shifts isn’t complacent, they’re “focused.” The relationship on autopilot isn’t neglected, it’s “stable.”
We dress up stagnation in the language of sophistication.
The antidote isn’t paranoia or the inability to enjoy achievement. It’s maintaining what psychologists call “beneficial anxiety”: the productive tension between satisfaction with where you are and awareness that the ground is always shifting beneath you.
The best athletes study film after victories, not just defeats. The best investors review their winning trades more critically than their losing ones, because they know lucky outcomes can reinforce bad processes.
At the height of Amazon’s e-commerce dominance, Jeff Bezos insisted the company operate with what he termed a “Day 1” mentality – the hunger and paranoia of a startup still fighting for survival. While competitors celebrated market position, Amazon kept acting like an underdog.
The emotional state that creates victory is different from the emotional state that victory creates. Don’t let the smell of success make you complacent.
