Hello and welcome to Spells of Magic! To do magick you read books, forums, articles, pdfs, etc. Then once you know what you want to do you put together a spell/ritual/working. So education and practice like most things. :)
Thanks for the question I'll do my best to give you my opinion.
I'm not so certain magic is something you actually acquire,
I believe it to be more or less a spontaneous instance that occurs during the practice of operations spells ritual etc. However one can obtain knowledge of the traditions they practice though understanding the origins practices rituals and history of any given tradition and as a result obtain the skills to perform complex operations that produce a magical occurrence.
