What is internal contracts self-agreement?

Example: You've been telling yourself for months that you'll 'balance work and rest.' But you never defined what balance means, never specified when rest happens, and never established what counts as a violation. The result: work wins every ambiguous moment because it's louder. Now try this instead — write down: 'I will work with full intensity Monday through Friday, 8am to 6pm. Evenings after 6pm and all of Saturday belong to rest and relationships. Sunday morning is for planning the week ahead.' That's not a wish. That's a contract between your achievement drive and your restoration drive, with specific terms both sides can reference.

This concept is part of Internal Negotiation in the How to Think curriculum.
