Know what communication really is.
Communication is the process of transferring signals/messages between a sender and a receiver through various methods (written words, nonverbal cues, spoken words). It is also the mechanism we use to establish and modify relationships.
Have courage to say what you think.
Be confident in knowing that you can make worthwhile contributions to conversation. Take time each day to be aware of your opinions and feelings so you can adequately convey them to others. Individuals who are hesitant to speak because they do not feel their input would be worthwhile need not fear. What is important or worthwhile to one person may not be to another and may be more so to someone else.
Make eye contact.
Whether you are speaking or listening, looking into the eyes of the person with whom you are conversing can make the interaction more successful. Eye contact conveys interest and encourages your partner to be interested in you in return.
Use gestures.
These include gestures with your hands and face. Make your whole body talk. Use smaller gestures for individuals and small groups. The gestures should get larger as the group that one is addressing increases in size.
