Trading is actually the most difficult profession to succeed in the world, and also the easiest profession to make money in. Young people should not touch it; those whose wisdom has not yet opened should not touch it; those who have not passed the emotional hurdles should not touch it; those who have not experienced the vicissitudes of life should not touch it; those who are unwilling to embark on the path of cultivation should not touch it. Only those who embody both Buddha and demon can choose this path. This is a path of inner cultivation, requiring good emotional management, an understanding of how to enjoy solitude, a top-level understanding of human nature, the courage to break self-perception, a gentle and cultured exterior, a decisive inner strength, and a focus solely on one's spiritual inner self, eliminating all useless social interactions. Only such a person can become a top trader.
