Are the spells you are trying even possible? ( spells to change what you are, alter your appearance or manifest something out of nothing are improbable)
Are you able to focus on your goal and keep out interruptions?
Do you have a basic understanding of magic (how it works, sensing and projecting energy etc.)?
If you answer no to any of these I suggest taking a look at the newbie section, and "The Basics" in the forums :D
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
