Nothing has worked because you have not studied the basics long enough!
Okay, so you've read a few articles, but were they about meditation, grounding, centering, visualization or energy manipulation?
If not then you have been reading the wrong articles, for now. Search for those in the forums to get a good idea where to begin.
Also, you need to know what magic is and how to work with it. Reading articles and getting a good idea about a spell, and then trying a spell, is the wrong way to go about it if you are totally new.
