Finally, you must have the perseverance and grit to stick to your principles. As Ben Graham noted, “If you believe that the value approach is inherently sound then devote yourself to that principle. Stick to it, and don ’t be led astray by Wall Street’s fashions, illusions and its constant chase after the fast dollar. Let me emphasize that it does not take genius to be a successful value analyst, what it needs is, first, reasonably good intelligence; second, sound principles of operation; and third, and most important, firmness of character.”
