Challenge in a world of talking

I came across with this statement: "Mentors in a world of talking: Children who are still in their formative years  need your expert handling of the English speech." The challenge is this: the image that we project of ourselves by the way we talk, does affect people's perception of us and of our profession. A public official who cannot enunciate well, a church preacher who shouts at everybody when under stress, a businessman who talks to his clients with plenty of grammatical errors, all these manners of communication for sure does not "speak well" nor "sound well" of the persons and of the professions they represent. We need to acquire good communicative skills if we are to be effective speakers in a world of talking.
