It would help if you told us which spell you were talking about. Saying "that wizard spell" really doesn't help us much. That being said, if it is a spell to turn you into one then no it wont work. In order to properly practice magic you must first take the time to study and practice the basics and then go on to spell casting. If you don't work for it, how can you expect results?
No, the spell wont work. In order for you to be a spell caster of any kind you need to, as previously stated, take the time to learn your basics and work toward the goal of working with magic and spell casting.
