Spells do not suddenly make your wishes come true. That's not how magic works.
With spells, you determine just what in particular you wish to happen and then cast a spell for that one thing to cause it to manifest. Of course, some spells will never work such as changing your physical body, levitation, flying, etc. Perhaps if you told us just what it is you want to accomplish we can suggest a spell or two that might make it happen.
There are no spells that will do that. Nothing will simply grant any wish you might have.
I think perhaps you don't have a good understanding of magic and spells.
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 likely 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
"The Veil's Edge" by Willow Polson
"Modern Magick" by Donald Michael Kraig
And the following links in this thread will also help you learn the basic skills necessary for effective spellwork.
One time though, I casted a happy spell and it worked without me doing that much preparation. It did say energy spell though so it might of just worked because it was an energy spell.
