He who regards many things easy will find many difficulties. Therefore the sage regards things difficult, and consequently never has difficulties.
LaoziOnce upon a time a man whose ax was missing suspected his neighbor's son. The boy walked like a thief, looked like a thief and spoke like a thief. But the man found his ax while digging in the valley, and the next time he saw his neighbor's son, the boy walked, looked and spoke like any other child.
Laozi
