What is Ulysses contract self-control?

Ulysses contract self-control is a concept in personal epistemology: The most important boundaries are the ones you set with yourself — limits on your own behavior, consumption, and tendencies that would otherwise undermine your goals and values.

Example: You have been telling yourself for months that you will stop checking email after 9pm. You know the pattern: you open your inbox intending to glance at one message, and forty-five minutes later you are composing replies to things that could wait until morning, your mind now churning with work problems at the exact hour your body needs to wind down. You have told yourself to stop. You have set intentions. You have felt genuinely frustrated with yourself at 10:15pm when you realize you have done it again. But the boundary keeps failing because it exists only as an intention — a promise from your present self to your future self, with no mechanism to make it stick. One evening, you try something different. You set your phone to automatically enable Do Not Disturb at 8:45pm. You move your laptop to a room you do not enter after dinner. You tell your partner that if they see you checking email after nine, they should ask you whether it is genuinely urgent. You have not developed more willpower. You have built a structure that makes the boundary enforceable. The boundary with yourself is no longer a wish. It is architecture.

This concept is part of Phase 33 (Boundary Setting) in the How to Think curriculum, which builds the epistemic infrastructure for boundary setting.
