除非一个人爱另一个人，否则他无法完全意识到另一个人的本质。
No one can become fully aware of the very essence of another human being unless he loves him.
意义来自于属于并服务于超越自我的事物。
The only limit to our realization of tomorrow will be our doubts of today.
In agriculture, patience isn't just a virtue; it's a necessity.
In the middle of difficulty lies opportunity.
劳动是创造财富的唯一途径。
时间并非实物，因此我们既无法浪费也无法节省；它始终与我们同在。
——2004年在南京航空学院上的演讲
