" I also discovered that the same principle works in a hundred different little personal ways. For example, I used to worry and fume about having to go to the dentist, and other unpleasant tasks. Then I said to myself, “This is silly. You know the unpleasantness involved before you make the decision to go. If the unpleasantness is all that important to cause so much concern, and not worth the worry involved, you can simply decide not to go. But, if the decision is that the trip is worth a little unpleasantness, and a definite decision is made to go—then forget about it. Consider the risk before the wheel starts turning.” I used to worry the night before I had to make a speech at a board meeting. Then I said to myself, “I’m either going to make the speech or I’m not. If the decision is to make it, then there’s no need in considering not making it—or trying to mentally run away from it.” I have discovered that much nervousness and anxiety is caused by mentally trying to escape or run away from something that you have decided to go through with physically. If the decision is made to go through with it—not to run away physically—why mentally keep considering or hoping for escape? I used to detest social gatherings and go along only to please my wife, or for business reasons. I went, but mentally I resisted it, and was usually pretty grumpy and uncommunicative. Then I decided that if the decision was to go along physically, I might as well go along mentally—and dismiss all thoughts of resistance. Last night I not only went to what I would formerly have called a stupid social gathering, but I was surprised to find myself thoroughly enjoying it. "
