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.
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。
I'm not a role model, I'm just a man.
晏子春秋
化学是在微观和宏观之间搭建桥梁的艺术。
