Usually, it is not the thing we are worried about which causes the biggest headache but the thing we are NOT worried about. If we are carefully monitoring a problem, we are far more likely to handle it well if, or when, it gets worse. But a problem for which no provision has been made, is a different kettle of fish. This second kettle may just fall on you, but even if it does, you will enjoy having other fish to fry. As long as you remain a little worried about what you are worried about, you need not worry about it!
