Before you proclaim to have found your Center, be clear with yourself:
Have you found YOUR Center?
Have you found THE Center?
Have you merely found A Center?
You may discover an Orbital Center- a point, tangible or not, around which revolution occurs. Your whole body, or a specific body part, may be an actor in revolving around a point.
You may discover a Geometric Center- a point, tangible or not, which is equally distant from two other points (again, tangible or not). In this context, there must be defined boundaries: No Edges, No Center.
You may recognize a Mutual Center- a point, tangible or not, which is both the mid-point between two defined edges as well the point around which orbital activity occurs.
Finding and knowing your Center requires, understanding the full Nature, and variety, of Centers.
