Education is a lamp, but too many never find the switch.
The most perfect education, in my opinion, is such an exercise of the understanding as is best calculated to strengthen the body and form the heart.
翻译：贤明的君主和将领，之所以一出兵就可以战胜敌人，成就的功业超过一般人，是因为他们能事先探明敌情。事先探明敌情，不能使用占卜的手段获取，不可用类比的方法获取，也不可推验日月星辰运行来获取。一定要取之于人，取之于了解敌情的人。
What I feared most for myself at your age was not poverty, but failure.
