It is foolhardy to make a second trade, if your first trade shows you a loss. Never average losses. Let this thought be written indelibly upon your mind.
Instead of hoping he must fear and instead of fearing he must hope. He must fear that his loss may develop into a much bigger loss, and hope that his profit may become a big profit.

The desire for constant action irrespective of underlying conditions is responsible for many losses on Wall Street even among the professionals, who feel that they must take home some money every day, as though they were working for regular wages.
I did precisely the wrong thing. The cotton showed me a loss and I kept it. The wheat showed me a profit and I sold it out. Of all the speculative blunders there are few greater than trying to average a losing game. Always sell what shows you a loss and keep what shows you a profit.
