“If I were to summarize in one sentence the single most important principle I have learned in the field of interpersonal relations, it would be this: Seek first to understand, then to be understood. This principle is the key to effective interpersonal communication.”– Stephen Covey, Author 「如果我要以一句話總結我在人際關係領域裡學到的最重要原則,它就是:先求了解對方,再求被對方了解。這個原則是有效人際溝通的關鍵。」– 史蒂芬‧柯維 (勵志作家)
