在面向听众讲话时，将目光固定在几个人身上比将目光 "扫射 "到整个房间更好。你的眼睛会向别人传达你是否相信自己说的话。
When speaking to an audience it’s better to fix your gaze on a few people than to “spray” your gaze across the room. Your eyes telegraph to others whether you really believe what you are saying.
The best ideas often come from the most unexpected places; keep your mind open.
The truth is rarely pure and never simple.
晏子春秋
