Ok, now. You say that you are both young and have NO magick experience.
Unless you have AMAZING Harry Potter style power in which it came naturally, without him even knowing about magick, then you will most likely not be able to perform even a simple spell.
I would reccommend going to this page: http://www.spellsofmagic.com/read_post.html?post=251089
This will teach you the basics, before you should attempt a spell.
If you are here to just find a spell TRY and perform it, and then leave into the great abyss of reality without intentions of returning, then this is not for you.
It WILL take time to be able to cast even the simplest of spells and that time will not be in only a matter of hours.
