Quote

The merchant must be no more pessimist than optimist, since pessimism induces him to hold back his capital but optimism induces him to take such risks that he has more to tear than to hope. Abu al'Fadl Ja'far al-Dimishqi (c. 9th century) Arab writer. The Beauties of Commerce Business pays ... philanthropy begs.
