There are three key traits: nonconformity, accountability, and self-control. The common thread among them is having “a personal system that continuously evolves.”

For example, when faced with negative events, some people only complain and vent, spreading emotional negativity without making changes. Others, while they might grumble or curse, never stop upgrading their system, working to eliminate the possibility of encountering similar issues in the future.

Let’s break down the specific traits, borrowing from the author’s mentioned points:

1. Nonconformity

Strength inherently implies being different from the majority. Fear of being different usually stems from a desire to cling to a sense of security, but choosing security often means forfeiting additional experiences and opportunities for trial and error. Strong individuals tend to make their own judgments about everything, even if those judgments turn out to be wrong.

2. Accountability

Strength isn’t innate—it comes from spending more time and going deeper into problems than others typically would. Such individuals rarely shirk responsibility and often take initiative to tackle problems that interest them, as long as they intuitively sense that the effort will yield future value or improve efficiency. Their trait is summarized as “less talk, more action.” When problems land in their hands, they often resolve them conclusively instead of deflecting blame onto others.

3. Self-Control

Strong individuals aren’t devoid of emotion; they simply understand that losing control won’t help them make progress. As a wealthy participant in a reality show about starting over from scratch once said, losing his temper during a business negotiation drastically weakened his bargaining position in a deal he couldn’t avoid, ultimately costing him profits. Strong individuals exhibit composure—they don’t make a fuss, rarely reveal their cards, and simply get things done with quiet efficiency.

From this perspective, strong people often resemble a “Yes Man”—open, adaptable, and willing to engage. They leave the door open for opportunities, working with anyone who comes knocking, even when it’s challenging. If the results fall short, they simply treat it as another opportunity to improve and grow stronger.

Of course, in reality, we don’t always have such resolve. We experience disappointment and fear, but the principle remains: you have to find a way to solve problems and make progress.

After all, mediocrity is truly the original sin.
