Just so.
The word I would use is ‘Sovereignty’.
Your center of Sovereignty, Personal Power, and Self-Determination.
It is, by its very definition, not dictated by someone else’s standards of normalcy, convention, or propriety. If it were, how could it be Sovereign?
It is the establishment of your Way of Being. Your Center.
And I really like that word you use ‘Legacy’. I feel that I haven’t yet developed to the point of considering it. It’s more aspirational for me. But I can feel that it’s right.
