: '''The 'Save More Tomorrow' Plan''' → A retirement plan where employees commit to "Save their FUTURE raises." Because the "Cost" is in the "Future," the "Doer" doesn't mind, but the "Planner" secures the money.
: '''Climate Change''' → The "Ultimate" intertemporal choice. The "Cost" is "Reducing our lifestyle today," and the "Benefit" is "A planet in 50 years." Humans are "Biologically bad" at this choice.
: '''Addiction''' → The "Total Victory" of the "Present Self." The brain's "Discounting Curve" becomes so "Steep" that the next "Hit" is worth "Everything," including the future of your "Health and Family."
: '''Deadlines''' → Why we "Crunch" at the end. As the "Deadline" gets closer, the "Future Cost" becomes a "Present Cost," and our "Bias" finally flips to "Action."
