First, start off with searching the forums for basics.
The basics are meditation, grounding, centering, visualization, and perhaps some energry manipulation.
There is much research, reading and practicing to be done. I would like to note though, that more than 70 percent of the spells on here do not work, but some do. With the help of your research and studies, you will come to find out which ones are logical and which ones are not.
But, I know you want to rush into this, but please do not. Take your time and enjoy the learning and the experience of your new found path.
