I agree with idiotbox, and if he doesnt mind id like to add
This world around us is OUR reality, created by us, each human (in quantum physic and mechanic sense) is their own god. The reality, or world, that is here now only exists because we want it to subconsciously, its here because we want something to live on. Therefore, once you have actually come to the realization of this type of thinking, you can ultimately change your reality.
And once you have come to that realization, anything is possible. I always think positive and have a positive outlook, i have come to this realization after watching 'What the Bleep do we Know?', which explains in more depth what i am talking about. I have changed my life, and it is a self-realization experience that sparks this kind of thinking.
just thought id give me 2cents ;P
