To make trades, you have to be fierce.

Many people have been struggling in this market for several years, learning a bunch of tactics, yet they are still hovering on the edge of losing money. Where is the problem? It's not that they haven't done their homework; instead, they want to learn everything and try everything.

So what happened? On Monday, I saw a breakout in the market and bought in. On Tuesday, I thought the price would rebound again and opened a position. On Wednesday, I saw bearish signals and decided to establish a short position. In one account, the bulls and bears were having a great time fighting it out, and in the end, I lost on fees and my mindset.

Every trading system sounds beautiful – some make a few points a day with short-term trading, some double their income monthly with medium-term positions, and some take long-term positions that soar. But you can't do all three at the same time. The contradiction between trading systems lies here – today's advantage could very likely become a burden in tomorrow's different system. Trying to fill the gaps by "learning a few more systems" instead amplifies the shortcomings and dilutes the advantages.

Bruce Lee's famous quote is classic: It's not about being afraid of an opponent who has a thousand techniques, but being afraid of him practicing one technique a thousand times.

The same applies to trading. Instead of casting a wide net to learn 100 methods, it is better to choose one that truly suits your style, refine it repeatedly, iterate continuously, and stick to its execution. Behind every system that can make money steadily, there is a corresponding single profit logic. You cannot have short, medium, and long-term gains all at once.

Choose one, called pure.

Practice a thousand times to truly master it.
