Hi Blake,
I wanted to comment on you finding the Old Ways. It sounds from your post that you are drawn to the basic Wiccan belief system. If I can give any advice it would be to focus on the beliefs, form your relationship with the Goddess and God, investigate through studying religion in history as well as mythology. These things are the foundation of Wicca and will help you determine exactly what you believe and why (which is very important). Another thing I highly recommend is meditation. I tend to be a little hyper so the thought of "sitting quietly" didnt really turn me on, but meditation is an active process and one that will truly reward those who pursue it. Since you have ADD, this may also be an excellent exercise for you to develop concentration and improve self-control. Meditation takes practice--so dont be discouraged, keep at it.
So, basically, my overall advice is not to worry about casting, summoning, banishing, etc right now. Those things will come if this is your path.
