Even introverts like to talk to other people sometimes, and it gets easier if you follow a few simple rules.
Mostly, we learn these rules by trial and error, sometimes called bitter experience. Boy, can the expewrience hurt. Ever had someone look over your shoulder to find someone more interesting while you're talking? That's one sign you may need to work on your skills.
Don't despair. You too can become an expert communicator. Start with some of these tips.
•  Speak more slowly. Your listener’s brain has to remember your  sentences, then decode the words and grammar before he can understand  your message. It takes time. Talk too fast and you’ll be misunderstood. 
 • Pause between phrases and sentences. Give your listener a chance to catch up and to react.
 • Use short sentences. You can only hold seven things in your memory at  one time. If you pack your sentences full, your listener will miss  something. Say important things as simply as possible.
 • Match your body  language to your meaning. How often do you say, “I’m listening” to your  child, while your eyes slide away to your computer screen or TV? Do you  ever say “yes,” while your expression says “no”? Avoid giving mixed  messages. 
 • Make eye contact with  your listener. She finds it easier to listen to you and you make a  connection: the eyes aren’t called “the windows to the soul”  for nothing. 
 • Check your tone of  voice. Sound impatient and that’s all your listener hears. He won’t  notice your words: we all know now that most messages come from our  non-verbal language.
 • Listen to the other  person. It’s so easy to plan your next sentences, forgetting to listen  to the answer. Watch TV interviewers and see how often they ask a  question that’s already been answered, because they forgot to listen.
 • Watch for the other  person’s body language. Notice his crossed arms or when he leans away from you,  showing that he’s feeling defensive. Watch when his body language  mirrors yours, showing he feels empathy with you. 
 • Give a context to what  you say. Don’t launch straight in to a set of instructions or  questions, but set the scene first. Your listener needs time to adjust  to the new topic. Phrases such as “can we talk about arrangements for  the weekend,” tune her in, help her start thinking and make it easier for her to  understand.
 • Take turns. Let the  other person finish what they have to say and avoid interrupting. This  matters even more in a tricky situation, when an interruption signals  that you are not prepared to consider another’s point of view.
