How to build such a kernel

Has anyone noticed that some people in the stock market remain very stable emotionally when facing market fluctuations and various positive or negative news? They never change their approach and can stick to their principles regardless of how the market shifts. In contrast, most people, when experiencing even slight volatility or minor disturbances, begin to doubt themselves or even change their minds, leading to chasing gains when there’s no signal or panic selling during downturns.

The fundamental difference between these two types of people is whether they have a “stable core.”

What is a “stable core”?

It’s not an innate talent but an internal order formed through postnatal cultivation. Like the reinforced concrete structure of a building, the core is the mental framework that supports us standing firm in wind and rain. People with a stable core are less likely to be swayed by external changes, their decisions are not disturbed by short-term fluctuations, and their actions are not hindered by temporary successes or failures.

How to build such a core?

Step 1: Extensive learning and reading

Knowledge is the foundation. Without enough knowledge reserves, any confidence is just an illusion. Systematic learning and deep research are not for show but to understand the essence of things. When your perception surpasses superficial appearances, you gain a framework for analysis and a basis for judgment when facing complex situations.

Step 2: Repetition and practice

Knowing and doing are separated by countless repetitions. True ability isn’t about how much you know but how consistently you can produce results. Through deliberate practice, internalize knowledge into instinctive reactions; through continuous application, turn theory into problem-solving skills. In this process, you will transform from awkwardness to proficiency, from tension to composure.

Step 3: Review and optimization

Growth isn’t just repetition but a spiral upward. After each practice, calmly review: what was done right, what was wrong, and why? This ongoing self-examination and adjustment help you approach the underlying laws of things and make your core more resilient through repeated refinement.

People with a stable core perform very differently in the stock market compared to those without one.

The stock market is the ultimate testing ground for human nature and rationality. Here, news changes rapidly, candlestick charts fluctuate unpredictably, and market sentiment swings wildly between greed and fear. Traders without a stable core are easily enslaved by emotions—blindly chasing highs during rallies, panicking and selling during declines—ultimately becoming the harvested “leeks.”

Top traders, however, their strength doesn’t come from predicting every fluctuation (which is impossible), but from a stable trading core:

They build their own trading system through extensive learning and research. They know which logic is worth investing in, which temptations to avoid, what patterns signal a buy, and what risks to steer clear of. This cognitive advantage allows them to hear truly valuable signals amid market noise.

They internalize trading discipline through repeated practice—setting stop-loss points and exiting decisively, entering trades when conditions are right. They don’t doubt their system after a loss, nor do they become overconfident after consistent gains. This consistency is key to long-term stable profits.

They continuously review and optimize their system—recording and analyzing every trade, learning from mistakes, and refining their approach. They understand that while markets and logic change, core principles remain constant.

It is through this process that traders evolve from “seeing mountains as mountains” to “seeing mountains as mountains again.” When others are anxious about short-term ups and downs, they remain calm; when the market falls into collective panic or euphoria, they stick to their judgment and act contrarily.

Ultimately, excellent traders not only achieve material gains but, more importantly, they fall in love with their calm, rational, and resilient selves through overcoming market adversity. Perhaps this is the most valuable gift that investing can give.

Building a stable core is a path with no shortcuts. It requires you to focus, practice bravely, and honestly face yourself. But the end of this journey is a state where, regardless of external storms, you can remain composed and at ease.

Whether you aim to achieve something in life or to maintain steady profits in the stock market, remember: external skills can be learned, but true strength always comes from the stable core you build through day after day of cultivation.

Extensive learning, thorough research, continuous repetition, persistent practice, ongoing review, and self-transcendence.

This is the real wealth you can carry with you—something no one can take away.
