Enough with the Chakras! Please. First off, ask yourself what you think a witch is, and why you think this. Look closely, and ask yourself why you may have thought of these things. Write those down, too.
Next i would suggest trying to connect with the elements. In my opinion a witch has a good connection with nature, and values learning. Learn what a witch is, i would suggest looking around witchvox, and possibly talking to some of the witches online here. If you can, i suggest looking in the articles section, and learning some of the basic's as well.
Grounding, centering, focusing, energy raising, visualization, ect.
i would also suggest trying to read AwakeTooLongs article on the basic's. The basics, and the basic's expanded!
