Precommitment
Precommitment is a decision-making mental model in which you deliberately restrict your future choices or make them more costly in order to protect your long-term goals from your short-term impulses. By binding your future self to a decision made when your judgment is clearest, you outsmart predictable self-sabotage. Originally studied by economist Thomas Schelling, it has broad applications in personal habits, addiction recovery, financial planning, and strategic negotiation.
