Nail Biting
Nail biting is a negative habit that often develops as a way to deal with undesirable stress. Just as with any other bad habit, it must be replaced with a good habit in order to be changed. The new, positive habit that it will be replaced with is relaxation.
You now realize that nail biting is just a way to deal with stress. You have now outgrown that behavior. Now you are informing your subconscious mind, the child within, that biting nails is no longer the way to deal with stress. Now that you are an adult, you want your nails to look healthy and strong. So from this point forward, whenever you have stress, you'll deal with it in a different way. All you need to do is simply take a deep breath and as you exhale, simply say to yourself quietly …
Imagine placing your hands up with your fingers extended outward right in front of you, and now imagine your fingertips and your nails looking exactly like you would like them to look. Visualize them clearly in your mind if you cannot imagine them in front of you. Just think about it and the same purpose is being served. This is what your nails should look like, and will look like.
Your subconscious mind is there every step of the way to help your fingertips heal and be healthy just like you are visualizing them right now. You have developed a new, positive habit of taking a deep breath as a way to deal with stressful situations. You are successful and you will remain successful every step of the way.
