Self acceptance is the first step of self confidence. No matter how much you try to imitate confident people’s moves, you can never be confident like you imagine. Accept your acnes, height, weight, shyness, coldness, sensitivity, weirdness, abilities and other physical and personal traits you have. Accept yourself as a whole. Don’t hesitate to face with the real you. If any improvement is needed, do it for yourself, your health and wellbeing, not to impress others.
