"Have you ever been told to quit biting your nails?" This familiar command has likely been directed at every child at some point. However, it can become incredibly frustrating when the habit persists, regardless of how many times you attempt to quit. Without even realizing it, you mindlessly nibble on your nails, causing them to become unsightly and painful once again. The true issue lies in the fact that nail biting is an unconscious behavior; you do it without even being aware. Thus, when you consciously decide to stop, nothing changes because the solution must occur on a subconscious level.
