Hey! Welcome to the path of magic :P
Magic is, for the most part, not something you can start up immediately. Every human has the potential to use magic, but it requires a tad bit of diligence.
First, ide recommend you read up on what Occult books you can. You'll learn much on the elements, what role they play, that type of thing.
Secondly, deep meditation (15 mins. a day at least) will further strengthen your connection. Once you've learned what is possible and understand more of magic, you pretty much can try whatever, whenever the need arises. Of course, there is a simple chant to raise your energy, if you want a practice spell.
"I am warm, warm as fire. All this warmth is my desire."
Keep your hands close, and your mind focused only on an image in your mind of a heat source.
Good luck :D
