A computer program is what tells a computer what do to, and the computer cannot do anything EXCEPT what it is programmed to do. Our brains are similar to the computer and our thoughts are similar to the program. Our brain cannot override the thoughts, but you can change the thoughts and therefore change the "program" in your brain. And, when we do, we change our lives. If you want different "outputs" in your life, then you've got to change the "inputs."
