Worry is a state of mind based upon fear. It works slowly, but persistently. It is insidious and subtle. Step by step it “digs itself in” until it paralyzes ones reasoning faculty, destroys self-confidence and initiative. Worry is a form of sustained fear caused by indecision therefore it is a state of mind which can be controlled.
