start with the basics. Basics are different for everyone so you must be patient. And sometimes a spell you cast will not always work though that is my belief. Also remember you reap what you sow. We have newbie central and many post on peoples ideas of basics. Do your studies learn to meditatie if you have not already...
Take your time with it and start with the basics. Wicca is a very big craft but you'll learn such wonderful things, so you don't need to rush. Just start with studying, learning about Wicca -how it came up, stories of Witches in history, The paths, The Sabbats, The deities, the beliefs that we have. theres a lot of interesting stuff out there, so just have fun with it.
Beginner magick is a good start, working with meditation, centering and grounding, visualizations, Casting/closing circles, Candle magick, Charms, Invocations, crystal work, for a few.
SpellsOfMagic is a really good site to learn, as they have a Article section, Spell section, and the forums-which is usually really positive and open to answer your questions.
