When willpower is not enough

HAVE you ever wondered why diets don’t seem to work in the long run? Or, why some of us really want to start exercising or use that gym membership which is now collecting dust, but it still hasn’t happened? Or, why those addicted to alcohol, smoking or gambling cannot seem to keep to their own promises to quit once and for all?

I’m sure we all know many friends and colleagues who have tried to go on a diet without success, or tried to eradicate an undesirable lifestyle or adopt a new one.
