To me, a witch is a woman that is capable of letting her intuition take hold of her actions, that communes with her environment, that isn't afraid of facing challenges.
For whereas the mind works in possibilities, the intuitions work in actualities, and what you intuitively desire, that is possible to you. Whereas what you mentally or "consciously" desire is nine times out of ten impossible; hitch your wagon to a star, or you will just stay where you are.
