More specifically, says Laibson, people perceive rewards and costs as having only half the weight tomorrow that they have today. In other words, unpleasant chores feel only half as bad when we imagine doing them tomorrow, versus actually doing them today.
“Pushing costly, unpleasant tasks into the future is like a getting a 50 percent discount on them, psychologically,” Laibson said. “When you actually arrive at that future date, you’ll once again face the same problem.”
