Worrying in itself is not a bad thing. It shows you care. When it gets to that constant and obsessive point, though, it inhibits success. You become paralyzed by fear of making a mistake, causing you to not act. Overthinking is a self-destructive behavior, taking a serious toll on both your mental and physical health. You will develop anxiety, which not only causes emotional suffering, but over time will affect your heart, digestive, and nervous system, as well as many other systems in the body.

You will have to repeat thoughts that challenge the anxiety hundreds, even thousands of times, because this is how often the cycle of worry has gone on in your mind. You have to put yourself into a place of power over your thoughts. It will also take a variety of exercises and coping mechanisms, such as yoga, meditation, and mindfulness. Don't panic if you don't know much about these. I'll tell you all about it. You are not at the mercy of your thoughts. They do not exist in the real world, or anywhere else other than your mind. They only become real if you create an intention and then follow through with action. This means your fears cannot harm you, only make you uncomfortable. Say you have a concer
