Scott Cunningham defines magick as the movement of natural (yet sublte) ENERGIES to manefest positive, needed change. Magick is the process of "rousing" energy, giving it purpose (through VISUALIZATION), and releasing it to create a change.
Wicca is the fastest growing religion in America today, and like fake Christins we have a such thing as fake Witches. They usually show their novice easily. If a man tells you he's a warlock this is true--although it has nothing to do with Witchcraft--because Warlock is a Celtic word(pronounced Keltic) meaning traitor or oathbreaker. They easily don't know enough to call themselves Wiccan. Also if they tell you that they did something spectacular like turninging people into frogs, changing their hair color without the aid of colorants. They're living in the cartoons.

What Wicca is
What Wicca Is Not
Wicca is not a light show--meaning that there is not instant hair colar change (if you want that join the Feria cult).
You are not special (other than the special your mother told you are) there's nothing hidden within you that will make you the Wiccan Messiah, give it up.
