When you’re faced with a temptation, e.g. when you have a sugar-craving, try this 15-Minute Rule: Commit to not giving in for 15 minutes. Take yourself away from the stimulus that led to the temptation.
With any luck, the enticement will wear off. At least it’ll become more manageable to control. If at all possible, wait another 15 minutes.
Idea for Impact: Self-control in the face of urges and cravings is a tricky thing. Even a simple distraction can break the trance.
