What is the most heartbreaking moment in trading? It's not how fierce the market drops, but the sense of resistance that rises from your bones when you lose money.

Some try to turn the situation around by adjusting their mindset, only to find it useless. In fact, it's not a matter of weak willpower, but a blockage at the fundamental logic of cognition—you're simply not understanding the true nature of losses, so the only reactions your brain can produce are denial and avoidance.

This cognitive gap leads many people down a seemingly reasonable but wrong path: desperately studying to improve win rates. The logic is straightforward—higher win rates mean more profits, right? But this is actually a mathematical trap.

Did you know? There is no causal relationship between win rate and long-term profitability. A system with only a 30% win rate can still do well if it strictly follows discipline, earning enough on each trade to offset several losses. Conversely, a strategy with a 90% win rate can be wiped out by a single unforeseen black swan event, where one loss consumes months of modest profits.

Where is the real dividing line? First, it's a breakthrough in psychological cognition. "Can't accept losses" means you haven't opened the door to trading properly; but "can't accept large unexpected losses" is the real technical issue—that tests your risk control ability.

Once you truly grasp the premise that "losses are inevitable," your entire thinking framework changes. Losses are no longer enemies to eliminate but costs that can be planned and managed.

So the focus shifts:

"How much am I willing to spend at most to endure this time?"

"How can I design this process to ensure this expenditure won't spiral out of control?"

"Can I rely on accumulating small costs over multiple trades to eventually catch an opportunity that covers everything and generates profit?"

This is no longer about mindset cultivation; it's about strategic planning and risk management. You start to plan losses like a business, set stop-losses with an engineer's mindset, and no longer fight against the emotions of loss but learn to coexist with them—treating them as an indispensable fuel to sail toward the shores of profit.
