While a lot of these are good behavioral techniques to project confidence, for the long term there is no substitute to create a healthy self-image that just makes you very cool to be around without even trying. Just like we have an opinion about our friends, people at work and so on, we also have an opinion about ourselves, both at conscious and subconscious levels. A lot of happiness and events in life stems directly from what opinion you hold of yourself. And eventually that opinion leads to a self-fulfilling prophecy...i.e. if you think you are no good in a particular setting, it eventually becomes so. A strong self-image can totally turn around your relationship with other people, your work and environment

To get started, try the book Psycho-Cybernetics...it contains a treasure of information to be acted upon... http://en.wikipedia.org/wiki/Psycho-Cybernetics
