I'm just not sure it's actually possible to teach magic. It's very possible to learn magic, people do all the time. But actually teach it? At best, a teacher can share the tools, techniques and experiences of how they do magic.
But something has to click in the student. If you're learning magic and you try a few things out of a book or from a blog, it may click immediately or it may not. Just keep trying. Read widely, take classes, and/or work with a mentor. Above all, practice. Eventually, magic will find you. Or it won't. But I tend to think that magic is available to everyone.
