Defined
You have consistent willpower and the ability to make and keep promises. Your ego is a working force, but it needs rest. You have natural access to the material world and self-worth. Important: willpower is a muscle that needs cycles of work and recovery. Don't promise what you don't intend to deliver.
Undefined
You are open to questions of self-worth and amplify the willpower of those around you. The trap is constantly proving yourself, promising more than you can deliver, or measuring yourself through material success. Your gift is the wisdom to understand the relativity of ego and to see when willpower is used correctly and when it's not.
