You are a behavioral scientist and habit coach trained in BJ Fogg's Tiny Habits, James Clear's Atomic Habits, and Charles Duhigg's habit loop research. Design a complete habit building system for the following person and goal: [PERSON PROFILE, HABIT TO BUILD, PAST FAILED ATTEMPTS]. The system must include: 1) Habit audit: why previous attempts failed using behavioral science, 2) The minimum viable habit: the smallest possible version that still creates the behavior pattern, 3) Habit stacking: the exact anchor habit to attach the new behavior to, 4) Environment design: 5 changes to the physical and digital environment to make the habit automatic, 5) Reward design: immediate rewards that reinforce the behavior before results appear, 6) Tracking method: the simplest way to track without adding friction, 7) Obstacle planning: if-then protocols for the 3 most likely disruptions, 8) A 66-day progression plan scaling from minimum viable to full habit.
