“We have seen much more money made and kept by “ordinary people” who were temperamentally well suited for
the investment process than by those who lacked this quality, even though they
had an extensive knowledge of finance, accounting, and stock-market lore.” –Ben
Graham
“Success in investing doesn't correlate with I.Q... Once you
have ordinary intelligence, what you need is the temperament to control the
urges that get other people into trouble in investing.” –Warren Buffett
