what changes words on a page into 'magic'? belief, energy, and desire. if you believe it will work, it will, if you put enough energy into your casting it will work, and if you desperately need something to come true your spell will work.
if you just read out of a book some words while lighting a candle, it mostly likely will fail. if you sit and meditate for a while holding each item, feeling the energy and reflecting upon what each will do to aid the spell, repeat the chant a few times to try to memorize it more, so you can visualize while saying it, then going out an working to achieve your goal then the spell will be successful. 'magic' is basically the energy one puts into a spell to make it work.
