I wanted to share one of Selden's quotes (there are so many of them that resonate). From Psychology of the Stock Market:
To a great extent we train our judgment to lend itself to our selfish interests. . . We cannot work for our own interests as in other lines of business--we can only fit our interests to the facts. . . To make the greatest success it is necessary for the trader to forget entirely his own position in he market, his profits or losses, the relation of present prices to the point where he bought or sold, and to fix his thoughts upon the position of the market. (p.57)
