Magic Forums

I've been to a lot of begginer forums and all that, and they all say in a sense, the same thing to start out with. Elements, grounding, visualizing, practice, and meditation. I understand all of that, but how do I do those things? Do I find my element by googling "What is my element?" Because that comes up with a bunch of quizzes. I have NO idea what grounding is, and haven't been able to find it. Practicing seems simple enough, because you just try again and again, but why practice? When you practice a spell, it doesn't work, it makes it very difficult to do it the next time, because you think 'Why should it work this time' Also I don't get meditating, What are you supposed to do? Think of nothing? Everything? Focus on surroundings? Breathing? Blood flow? Can you be laying down? Stand up? Thanks for all the specifics :D
