Jim Kwik argues that belief drives behavior, and behavior drives results. Your self-talk programs your brain like a supercomputer: tell yourself you can't remember names, and you won't. One negative thought doesn't matter, but repeated ones accumulate and shape what you become.

All behavior is belief-driven. If you want to create a new result in your life, more money, healthier body, better relationship, whatever it is, if you want to create new results, you need to do a new behavior. In order to do that new behavior, it's required a belief that says that behavior is possible because all behavior is belief-driven. Your brain is this incredible supercomputer and your self-talk is the program it will run. So if you tell yourself, I'm not good at remembering people's names, you will not remember the name of the next person you meet. Because you program your supercomputer not to. That's how powerful your mind is. If you truly understood how powerful your mind is, you wouldn't say or think something you didn't want to be true. And that's not to say you have one negative thought, it ruins your life. Of course not. Any more than eating that donut will ruin your life. But if you ate that donut 20 times a day, every single day, will there be a consequence? And so you need to own your self-talk.
