I suggest do more studying, reading, and watching! I suggest you click the home page and click the newbie central. Once your done with that I want you to click on videos. Search and look up your questions about it. After that I suggest studying what shamanism is. You want to be a wizard? What do you mean? A Witch? Don't worry... you'll embrace the label as you go along!
What path do you want to follow? Witchcraft, Wicca, or what?
I suggest reading books, if you cant fine any just google them.
