What is behavioral activation environmental cues?

Example: You committed to writing every morning before work. Commitment Architecture taught you to make that commitment binding — you told your accountability partner, you installed a site blocker, you wrote the implementation intention. But you keep sitting down at a clean desk with no manuscript in sight, opening a blank document, and losing five minutes to setup friction before the writing begins. So you change the environment: every evening, you leave your manuscript open on the screen, your chair pulled out, your coffee mug beside the machine with grounds already loaded. When you walk into the room at 6 AM, the room is already writing. The commitment device keeps you from defecting. The environment keeps you from stalling.

This concept is part of Choice Architecture in the How to Think curriculum.
