Your view of yourself will greatly influence how others perceive you. If you are a confident, cheerful, positive person, your co-workers, friends, and family will be attracted to your personality. If you are unhappy, negative, and always complaining about your situation, others will be repelled. Even when at times you don't feel very happy, by forcing yourself to behave in a positive fashion, you will find that you soon feel genuinely upbeat, because your subconscious mind doesn't know the difference between an artificial emotion and the real thing. When you behave positively, you will positively influence everyone around you -- including yourself.
