Here is exactly how to change your focus of attention from failure and worry to success. Notice what happened to your thought processes as you focused on the first sentence. Now, just for contrast, focus on the other sentence. Notice your resulting thinking. In 13 years of success coaching, my experience with myself and my clients is that this belief is inaccurate.
People can simply change their actions in order to change their results.
He refers to a client who had spent 18 years in therapy before she came to him because she was trying to figure out why she bit her fingernails. She was to return for her session next week, and in the meantime she was not to put her fingers in her mouth. She could talk about biting her nails, but she was not to actually do it. Focus your attention differently. Whatever you choose to focus your attention on is what you are believing in, in that moment.
