There is only one reason why people will like you and that is "you make them feel good."The Enneagram is a systematic and dynamic model mapping "what, why, and how" we think. We all have a core need and meeting that need is essential to be liked. The Enneagram shows us what that need is. "One Reason" is written with teenagers and young adults in mind. It shows we identify core needs through observation and listening what people say. And that is invaluable for making friends, gaining alliances, and cooperation.
