Communicating effectively means more than knowing what to say and when to say it. Communication involves the subtle signals your body language sends to those who are watching. Here are some common body actions and the impressions they create:

● Fiddling (好动) — Playing with your watch or a pen looks like you’re bored or impatient.

● Clock watching — It looks like you’re to move on to something else.

● Tapping  — Tapping your feet or fingers suggests you are impatient or nervous.

● Staring — An unblinking (不眨眼的) stare conveys threatening or violent behaviour.

● Legs crossed or body hunched (弓背,耸肩)  — Closing up your body profile — becoming smaller — looks like you lack confidence.

● Arms crossed  — If you keep your arms folded during communication, you appear to be defending yourself against the others.

● Touching your face  — When you have your hand in front of your mouth, you appear very shy.

● Rubbing your nose, looking away  — People who are lying often rub their nose or look away when speaking.

● No eye contact  — If you won’t look the other speaker in the eye, you seem to have low interest or a lack of confidence. (Don’t forget staring above.)

How you communicate with your body language is just as important as what you say. Watch your body language and control the unconscious messages you might be sending.
