“A trader, in addition to studying basic conditions, remembering market precedents and keeping in mind the psychology of the outside public as well as the limitations of his broker, must also know himself and provide against his own weaknesses. There is no need to feel anger over being human. I have come to feel that it is as necessary to know how to read myself as to know how to read the tape. I have studied and reckoned on my own reactions to given impulses or to the inevitable temptations of an active market, quite in the same mood and spirit as I have considered crop conditions or analysed reports of earnings.“
