Predicted that most people who apply the 7-day rule for purchases will forget about the item and not buy it after 7 days.
"The trick behind this is pausing for 7 days before you buy anything. Then after those seven days are up, ask yourself again if you still want it. Most of the time, the answer will be no. After waiting 7 days, you often forget all about it as the excitement has faded and it wasn't that important to begin with."
