Worry is a complete waste of time and creates so much clutter in your mind that you cannot think clearly about anything. The way to learn to stop worrying is by first understanding that you energize whatever you focus your attention on. Therefore, the more you allow yourself to worry, the more likely things are to go wrong! Worrying becomes such an ingrained habit that to avoid it you consciously have to train yourself to do otherwise. Whenever you catch yourself having a fit of worry, stop and change your thoughts. Focus your mind more productively on what you do want to happen and dwell on what's already wonderful in your life so more wonderful stuff will come your way.
