Instead of thinking that what you want is not going to happen, think that it will.  Think not of where you are coming from, but where you are going to.  Instead of thinking that you are at your end, think that you are at the beginning and everything is brand new.  Thank past your limitations, fears and doubts, think past your failures, setbacks, obstacles and roadblocks as if they don´t exist.  Think that things aren´t happening to you, they are happening for you.  Think about what you have, instead of what you think is missing.
