You could not have survived your childhood without your ego. Your ego helped you to understand yourself as an individual. It enabled you to stay safe.
As you grow into adulthood, your ego, if left unchecked, will cause problems. Your ego likes to keep you doing the familiar. It loves the status-quo.
Your ego wants to keep you safe, but it is robbing you of new and exciting experiences. Anytime you try something different, it will do its best to stop you through the inner critic’s negative voice.
A great way to stop your ego from controlling your life is to learn the psychological-spiritual tool called the Enneagram.
