"If you're dieting, for instance, you may easily resist the blueberry muffin at that impossibly aromatic bakeshop you pass by in the morning.

You find yourself declaring after dinner that, yes, you will take a look at the dessert menu. I will have a slice of that creamy cheesecake, you say. After all, what's a little indulgence after a strenuous day of healthful living? Psychologists have long observed this pattern with self-regulation. They liken a person's self-control to a muscle's diminishing power; that is, the more people use their limited supply of self-control to stop one behavior, the more likely they will succumb to the next temptation.
