I have been a witch for many years myself.... First here are some building blocks to ponder. It's called the Witch's Pyramid and here is a simple version of it...
FAITH: you must believe in yourself and what you are undertaking. Put faith in Yourself and the Deities (God and Goddess) with all your heart.
WILL: You must have the willpower to complete what you start. You can't just stop in the middle of a ritual because the phone rings and it's your best friend wanting to chat or you decide tomorrow will work better for you. Willpower is also the inner ability to make results happen.
IMAGINATION: Without being able to open your mind to "whatever" you reach for, you will never achieve your desired results. This is "KEY" to working within the craft! In other words, you cannot open up to spiritual growth or commune with the Deities without opening your imagination to "ACTUALLY" do it.
SECRECY: This is knowing WHEN it is alright to talk about it...TO ANYONE! There is a saying "knowledge shared is Power lost" All the energies around us that we work with and within carry a negative, as well as positive aspect. If you were to tell someone, and they don't like you for it, they "can" send out negative energies at you which can actually be harmful, if you are not totally protected. I don't "tell," because I care not to deal with the negative it may cause. There is a time to share, and those to share with, but learning to keep silent is so valuable.
There are books to read... Scott Cunningham is/was a good author about the Craft. There are many other books and authors to discover... However.....The best "basic" book out there may just be (no, not kidding) "Idiot's Guide to Wicca and Witchcraft."
Website-wise: Witchvox.org is a good site. But that is just the beginning on the web...
There is so much information out there to be found and so much to hunt through. Just remember, that whatever you decide to do, wherever your path may take you... ALL spells, incantations and so forth should be written BY YOU and your Book of Shadows is HAND written...not copied pages taken from a web site!
Good Luck, Blessed Be to you.
