In the workplace, the most effective communications are usually:     1) clear,  2) concise, 3) coherent, and 4) comprehensible (to your particular audience). 

Good listening is the key to good communication--listening mindfully to others and to your own inner self.

Most of what we understand about others comes from their nonverbal communication: facial expressions, eye contact, gestures, tone of voice, general mood, and level of energy.

Different individuals and cultures have different speaking and listening styles.  It is important to take into account the needs and communication styles of your audience when trying to communicate your message.

Good communicators use a variety of communication modalities to accommodate diverse listening and learning styles.   These modalities include: oral, written, visual, aural, and kinesthetic.

One way to determine if your message is clear is to put yourself in the position of the listener.

Another way to determine if you have presented a powerful and persuasive message is to ask yourself the following questions:      1) Did I explicity state the main point of my message? 2) Did I present the subpoints that support my main point?  3) Are those subpoints in a logical order?  4) Did I offer detailed examples to illustrate my subpoints? and 5) Did I discuss these examples in sufficient depth?
