The wise man, after learning something new, is afraid to learn anything more until he has put his first lesson into practice.
LaoziWhen a country is in harmony with the Tao, the factories make trucks and tractors. When a country goes counter to the Tao, warheads are stockpiled outside the cities. There is no greater illusion than fear, no greater wrong than preparing to defend yourself, no greater misfortune than having an enemy. Whoever can see through all fear will always be safe.
Laozi
