Gain greater awareness of the "tone of voice" of other people. Listen to the way people speak when they are joyous, when they are cheerful, when they are upbeat. Listen to the way people speak when they are calm and relaxed. And listen to the ways people speak when they are impatient or angry.

Let every positive tone of voice serve as a reminder for you to speak with a pleasant tone of voice to others. Let every negative tone of voice serve as a reminder for you not to speak that way to others.
