People do evaluate you on the basis of your appearance. A positive image can be obtained by using of eye contact, voice and tone of speaking, dress and hairstyle. One way to project a successful image is through faster movements. Most confident, successful business people walk and move faster than average. Their movement indicates they have someplace important to go, something important to do and use time efficiently.
Nothing conveys self-confident more than good posture.
Check your posture as you pass a mirror or window. If your answer is yes to most of these questions you are probably telling the other person that you will not be working very enthusiastically and energetically for them. Your sitting posture often indicates the interest and concern for the other person. After you are seated your feet should be perpendicular to the knees, hips even on the chair, spine straight,head up and hands relaxed. Direst eye contact is another way to convey interest in a person you are talking with.
