Trading for many years, from a novice losing money by chasing gains and fearing losses, to a stable trader who understands and acts in harmony with principles, I finally realize: trading has never been a game of seeking huge profits, but a long-term practice of confronting human nature, coexisting with rules, and reconciling with oneself. The market is never short of smart people; what is lacking are those who can control their desires, adhere to discipline, and respect risk. All short-term luck-based profits will eventually be returned to the market, only systems, mindset, and risk management can enable us to stand long-term in the capital markets.
