Whenever you have strong negative feelings because unfortunate things are actually happening to you or you imagine that they might occur, see whether these feelings healthfully follow from your wishes and desires to have better things occur. Or are you creating them by going beyond your preferences and inventing powerful shoulds, oughts, musts, demands, commands, and necessities? If so, you are turning concern and caution into overconcern, severe anxiety, and panic. Observe the real difference in your feelings!
