Whatever your grade or position, if you know how and when to speak, and when to remain silent, your chances of real success are proportionately increased.

The language is a means of verbal communication. People speaking the same language convey messages this way, but sometimes keeping your mouth shut is the best answer ever. Only this way can you make a good impression to the people surrounding you, ethier if you are the head of some company, or an ordinary person. Listen more, and talk less.
