I may be just guessing here and putting my foot in my mouth. But here goes anyway. By "summoning stuff",do you mean demons? first with magic, you have to start with the basics. master those and go from there.And if your talking about summoning demons- once again, I am guessing here. You are way way over your head.and summoning demons or anything before you have a good strong magical foundation, You are in for a world of pain and trouble.
Magic takes time patience and commentment.
