Hi and welcome to SOM, here are some starter links to assist you:
Before you do anything like a spell or a ritual in witchcraft you must know how magick work and what is magick
Also I suggest that you have a look at these books
Wicca: A Guide for the Solitary Practitioner by Scott Cunnigham
Living Wicca: A Further Guide for the Solitary Practitioner by Scott Cunnigham
The Truth About Witchcraft by Scott Cunnigham
Divination For Beginners by Scott Cunnigham
Welcome to SOM and we can't make you believe. That's entirely up to you, I myself can careless if you believe or not. It all comes down to you and your faith. I can tell you that magic is real and that's because I believe it is and have had great results. But, just because I believe in it dosen't mean you are, so you must explore yourself and your beliefs. For a spell to even work you have to have confidence in yourself and the energy and intention on that spell to work successfully. Like, I stated before it all comes down to you and what you believe in. If you don't believe magic is real, then of course your never going to go anywhere with magic. Educate yourself on the topic and you make the decison if you believe or not.
