Good for you. At least you are believing in what you want, and keeping in open mind. That's what is called a good skeptic. But the best proof, is the one you show yourself. I didn't quite, totally believe in this till I did it. Videos? psh...they didn't convince me.

But, I tried it out, and violah! I got it working, and now I believe in it fully. It's just a matter of having an open enough mind to try it out. ANYONE and EVERYONE can do these things. All it takes is some belief, some dedication, and the time to practice. And I guarantee you will see success. So don't look for someone else to find proof, don't be lazy! Just show yourself that it is real!
