What exactly can trading earn you? I've been asked this question countless times.

The truth is this—only a very small number of people can make enough wealth from trading to live comfortably and then walk away; a few treat it as a livelihood, and although their income may not necessarily be higher than a regular job, they at least escape the routines of the workplace and live more freely; as for the vast majority? They carry debt, hold onto regret, exhaust their youth, and feel sorry for those around them.

Why is the gap so big? Simply put—it's all about your level of understanding, discipline in execution, and trading system.

Most failures come down to similar reasons. After making some money, people get greedy and increase their positions; after a big loss, they panic and continue throwing money at the market to fight back, eventually getting wiped out. Or they underestimate small losses, only rushing to double down after losses accumulate to a certain point, ending up as victims of market manipulation. These are all manifestations of human weakness—greed, fear, and luck.

"The great wind rises from tiny ripples," your trading account collapsing often begins with a small human weakness getting out of control.

What to do then? Instead of fighting human nature, it's better to set rules to cage it. Clarify your trading direction, entry cycle, and decision criteria. Know when to cut losses and when to take profits, and recognize what failure signals look like. In simple terms, develop a complete risk management system.

Those who truly understand trading know this principle: the market's money is earned through rules, and losses must also stay within the scope of rules. Profit and loss are actually two sides of the same coin; the key is—don't rely on rules to profit, but instead avoid erosion caused by human weaknesses.
