There's one sure fire method. Step one, realize what you're trying to perfect, step two research and read about it, step three practice. There are no shortcuts in magic and any spell which claims to grant you immediate experience is frankly a pile of rubbish. The key to perfecting any skill both magical and non is practice and patience.
As a final note it's important to realize what is and what is not possible. As you didn't specify what "ability or power" you were trying to develop I'll state now that magic works within the laws of the universe, that is to say that it is never going to grant you the ability to shape shift, throw objects with your mind, create fire from nothing and a great many other things seen in the works of fantasy.
Spells don't give you abilities or powers. What exactly were you trying to do with your spell? Do you understand how and why magic works, or are you just trying to read a spell off this site and hope it works?
Well, if you're serious about learning how to do magic and with starting from the rock-bottom then you don't start out by casting spells, you start out by learning how and why magic works.
You see, there is no such thing as an "easy" spell or a "beginner" spell. One either understands how magic works and has mastered the basics...in which case the magic will work..or you haven't done that sort of work..and no spell will work no matter how "easy" it seems.
Casting a successful spell involves much more than finding some spell on the internet or in a book, saying some words, lighting a candle, waving a wand of any of that sort of thing. In order for magic to work you need to understand how and why it works in the first place. Grounding and centering, visualization, focus and intent, energy manipulation, etc are all necessary first steps to even begin to have a chance at a spell actually working...and more importantly to prevent a spell from back-firing on you.
So, my advice for anyone who is truly serious is to start by reading a few books and practicing the exercises those books will give you. Once you have mastered the basics you won't need anyone to give you spells, you'll be able to create your own spells that will be far more effective than anything you find on the net. Here's the books I suggest:
"Before You Cast a Spell" by Carl McColman
"Spells and How They Work" by Janet and Stewart Farrar
You might consider staying away from fluffy subjects. Your bio says you want to practice Frigokenesis. This is fantasy.
