You do not need fight Worry – that isn’t the way to overcome the habit. Just practice concentration, and then learn to concentrate upon something right before you, and you will find that the worry thought has vanished. The mind can think of but one thing at a time, and if you concentrate upon a bright thing, the other thing will fade away. There are better ways of overcoming objectionable thoughts than by fighting them. Learn to concentrate upon thoughts of an opposite character, and you will have solved the problem.
