Based on popular temperament theory, dating back 25 centuries there are four basic personality styles. Each personality style has certain values and needs that drive their behaviour. If those values and needs have been properly met and nurtured you will feel whole and authentic. If the needs and values have not been met, you will be often acting 'out of esteem'. The way we communicate both positively and negatively give us clues to the real authentic self. What colour is your communication?
