EXPERIENCE is the key to casting spells. Most practitioners that cast spells have been in the craft for years or it was passed down to them by family. Casting Spells is not something you can learn over night and it's nothing like what you see on television or the movies. Take time to learn the Basic's of Magic and how to properly Meditate before you try jumping in head first with something you don't understand. I am not trying to discredit anyone or be mean but it takes more than a few days or months to learn about magic and how it truly works.
I also posted this same thing in the welcome post. Please use common sense when reading spells on this site or any other site as not all spells are true or can be preformed. Sorry.
