The only way to have a friend is to be one.
唯一交到朋友的方法就是自己先成为朋友。
Every song on stage is my true voice.
The only limit to our realization of tomorrow will be our doubts of today.
心理学必须是一门现象的科学,而非本体。
On choosing friends: "Life's too short to hang out with people who aren't resourceful."
The reward of seeing the joy on the faces of the parents is immense.
