How to deal with losses in the recent market?

The profit and loss results of opening an order are often a combination of "decision quality + luck." Good decisions do not necessarily lead to good results. Quality decisions represent your independent thinking and betting on a direction with a higher probability, but most of the time we irrationally take risks due to short-term trends and attractive profit-loss ratios, desperately trying to prove how clever we are, while forgetting the uncertainty of the market and that both good and bad results occur with certain probabilities.
Everyone emphasizes the trading system, which cannot be established by retail investors in just one or two years, especially since knowing is easy but doing is hard. My insight is to first establish probabilistic thinking, optimize my decision-making process, transition from a gambler's mindset to seeking the basis of probability, and shift focus from results to the process. If the process is correct, leave the results to the market. This way, there won’t be a situation where if I gain, I say "I was right"; if I lose, I say "I was wrong"; or worse, say "the market was wrong," leading to significant losses.
