Ten years' time, to compress all the psychological torment one should experience in a lifetime, repeatedly enduring it over and over again. Merely enduring is not enough; one must also review oneself daily and make incremental changes. The depth of change directly correlates with the depth of feedback in the account.

Those who change little lose quickly; those who change more lose slowly; only those who completely transform themselves can start earning. It sounds simple, but in practice? The vast majority of people cannot do it.

All the things that need changing are ingrained in a person's bones—the instinctual codes written into their genes, survival programs that have evolved over millions of years. It is this set of programs that has made humans the rulers of the Earth. Ironically, these innate instincts and natural tendencies, which are invincible in the natural world, become poison in the trading market, almost guaranteeing a margin call.

Human nature is characterized by certain flaws: a dislike for deep thinking, a habit of following feelings; forgetting principles when seeing small profits; being strict with others but lenient with oneself; always finding excuses; disdaining rules and preferring shortcuts; stubbornly holding on during floating losses and rushing to close during floating gains; making solemn promises before placing an order, then forgetting everything once the market opens; emotional buildup leading to impulsive actions; when gambling instincts take over, frequent trading, directly opposing the market... All these issues need to be rooted out, one by one.

Some problems are easier to fix; after losing once or twice, one learns the lesson. But some bad habits are particularly stubborn; after dozens or even hundreds of losses, they still cannot be changed. Even more heartbreaking, there are some operational traps that one might not even notice, and by the time they realize, the cost has already been paid.
