One of the worst features about worrying is that it destroys our ability to concentrate. When we worry, our minds jump here and there and everywhere, and we lose all power of decision. However, when we force ourselves to face the worst and accept it mentally, we then eliminate all those vague imaginings and put ourselves in a position in which we are able to concentrate on our problem.
