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 who lack wisdom should not touch it, those who have not passed emotional trials should not touch it, those who have not experienced the world's affairs and the warmth and coldness of human relationships should not touch it, and those who are unwilling to embark on the path of cultivation should not touch it. Only those who embody both Buddha and demon will choose this path; it is a path of inner cultivation. One must be adept at emotional management, understand how to enjoy solitude, have a top-level understanding of human nature, dare to break self-perception, appear gentle and refined on the outside but decisive and ruthless on the inside, focus solely on one’s spiritual inner self, and eliminate all useless social interactions. Only such a person can become a top trader.
