Basically when you study and practice Witchcraft, and you do your best to be a good person, you will become yourself, or you will decide that this is not for you and move on. Witchcraft is not the perfect answer to everything. You have to want to learn and be willing to question everything, even yourself. But if this is where you belong then it can mean empowerment and freedom. This practice will change your perceptions of reality, but it is no excuse to not live in the practical world as well.
Witchcraft is a never-ending challenge on many levels.
You may be ostracized by peers and family, or you may loose your job security. This practice can entail a powerful social burden, which is why the perpetuation of myths and half-truths hurts the practitioners of Witchcraft so very much. Those awful movies and the silly people who emulate them throw fuel on a fire that has been burning us for thousands of years. But it is a passion for me, and not even death can drive me from it. Lighten up and study the issue, whether you want to be a Witch or warn others away.
