In going over the original version of How to Fall Out of Love I was impressed by the advantages of a systematic program. It really does help to observe and organize your feelings. It helps, because as psychologist Dr. Herbert Fensterheim has shown, once you observe your feelings, you objectify them and gain perspective.
Gaining perspective lets you see your feelings from a distance.
That distance makes your feelings less overwhelming and easier to handle. It also helps to have a step-by-step program of positive things to do rather than struggle with an tide of amorphous, overwhelming feelings. And it helps to have specific goals so you can measure your progress.
