Worry serves no useful purpose and can have a serious adverse effect upon your mental as well as your physical health. Charles Mayo, who with his brother William founded the famous Mayo Clinic in Rochester, Minnesota, said, “I have never known a man who died from overwork, but many who died from doubt.” Because worry is directed at some vague, uncertain threat, it is difficult to deal with it logically. The best way to get rid of your worries is to take positive action to eliminate their source. When you develop a plan for dealing constructively with problems and get to work implementing your plan, you will no longer be troubled by worries. Negative thoughts always yield the right of way to a determined person in pursuit of a positive plan of action.
