The most effective people never change from one situation to another. They're the same whether they're having a conversation, addressing their garden club or being interviewed for a job. They communicate with their whole being; the tones of their voices and their gestures match their words. (Para. 7)
Meaning: The most effective people remain consistent in all situations. They act in the same way whether they're talking with others, or they're giving a speech to others in their garden club, or they're being interviewed for a job. They communicate not only with their speech but also with their eyes, faces, bodies and attitudes; the tones of their voices and their gestures are consistent with their words.
