The biggest gain in 2025 is realizing the shortcomings in various trading practices and telling myself that I can do better next time. At the same time, I also understand that you cannot find the right answer in the wrong direction or target, and timely loss-cutting should not be a 'mental demon' that entangles or torments your mindset, but rather a reflex action like slowing down and stepping on the brakes when encountering a red light or obstacle. We are not afraid of failure; we are afraid of not having the 'spirit' to try again and the capital to achieve our dreams. The reason for cutting losses is simple: to preserve your opportunity to try again.
