The reason is that a man may see straight and clearly and yet become impatient or
doubtful when the market takes its time about doing as he figured it must do. That is
why so many men in Wall Street, who are not at all in the sucker class, not even in the
third grade, nevertheless lose money. The market does not beat them. They beat
themselves, because though they have brains they cannot sit tight. Old Turkey was dead
right in doing and saying what he did. He had not only the courage of his convictions but
the intelligent patience to sit tight."
