Where I can learn magic and witchcraft?

I really want to strengthen my psychic abilities. I had some as a child, but I needed to block them out to function in school and such. I'm just starting to get back into witchcraft and I could really use pointers.

I know google magic is risky, so do you want to help me? :) Any knowledge you can provide would be appreciated. Beginner spells, reliable websites, general advice? I'm all ears.
