Trading mentality cannot be cultivated, but can only be tempered. Ten years of theoretical learning is not as impressive to traders as one month of real trading experience. Modern medicine believes that the human brain is divided into a subconscious area controlled by the pituitary gland and a conscious area controlled by the cerebral cortex. The two areas inhibit each other, and only one can dominate and control the human body to make different decisions. Medicine has proven that when people face fear, the human body's blood will rush to the pituitary gland. At this time, the subconscious will dominate people's decision-making. Rationality is suppressed, and people will become anxious about gains and losses and eager for quick success. After experiencing and being able to endure this pain, traders can grow and are no longer disturbed by market fluctuations. The cerebral cortex dominates. Trading within rationality and rules, the profits that were previously sought but not obtained have become something easy to obtain.

Of course, this does not imply that people should be grateful for suffering and the people and things that cause suffering, but that when we face suffering, we must learn to face it bravely, grow in suffering, and temper our psychological resilience under pressure.
