Do you ever look around you and think you´re the only one making any sense? Or tried to reason with your partner with disastrous results? Do long, rambling answers drive you crazy? Or does your colleague´s abrasive manner get your back up? Do you ever get the feeling you´re surrounded by idiots? You are not alone. Swedish behavioural scientist and runaway author Thomas Erikson is here to help, and will inform and entertain you in equal measure. This book presents his simple model based on four personality types (Red, Blue, Green and Yellow). When you understand the psychology of each you can adapt your communication style to handle anyone more easily and get the best out of the people you have to deal with - be it at work, in public or at home.
