Hello: I would strongly recommend you learn thebasics,if you have not done so. They will build the foundation to let you control and cast spells, But as stated previously what do you want to prove,that you are a witch or different than every body else? Witches are not in it for ego,power trips or any mundane issues. I use my abilities to help those who ask for help in their issues. Please learn the basics and after that cast toyour hearts content as long as it causes no harm.
Excuse me for intruding, but "witch" does not mean "wise woman." Its origins are in Middle English and Old German and the precursors had meanings ranging from "magick user" to "divination" to "holy."
There is no mention of wisdom and the only relation to femininity it had is that the modern pronunciation is closer to the feminine form of an old word meaning "magician" than it is to the masculine form.
A witch, by any definition originating in linguistics rather than cheap Wicca, refers to one who uses magick. Since that is literally all the word entails the heart of your original point still rings true: why MUST you perform magick? It is only one of many tools at human disposal and it is not necessary to be a practitioner of a traditionally magickal faith like Wicca.
