The challenges in life can be divided into two broad categories: those things you can’t do anything about (like the weather); and those things you can do something about. Don’t worry about the first category, because there’s nothing you can do about those things. Don’t worry about the second category, because if you can do something—do it, don’t worry about it! Many years ago, I learned a little poem that has helped me overcome worry. It says, “For every evil under the sun, Either there is a cure, or there is none. If there be one, seek ’till you find it. If there be none, never mind it!” Jesus said, “Do not worry” because it’s a waste of time!
