The Secrets of Better Communication from the Masters
Know yourself
Know your topic
Know your audience
Communicate in the language, slang, dialect of your audience
Be simple, relevant, enlightening. Make clear your ideas by using examples, analogies, anecdotes, stories, "great words", and images, symbols and archetypes that are shared by most (if not all) of your audience.
Avoid jargons as far as possible (unless your audience know them and use them) and when you use it, define it clearly
Keep your sentences, paragraphs short and simple. Avoid complex and complicated sentences. Avoid double negation etc.
Use a pleasant and confident tone (or the tone that corresponds the content and affection being communicated)
And above all, have a clear, serene, tranquil mind. Only such a mind can organize and present ideas effectively.
Be receptive to people, and K. Listen actively.
Avoid stuttering/stammering, avoid referring to notes while you speak, use memory effectively. Be fluent.
Communication becomes difficult without a clear and vivid memory. Memory of faces and names of people and things, situations, words of others are also very important.
