What is self-monitoring cost?

Self-monitoring cost is a concept in personal epistemology: Monitoring itself costs attention and energy — the overhead must be justified by the value it provides.

Example: You decide to track your daily habits with meticulous precision: sleep quality on a 1-10 scale, time in bed, time asleep, number of awakenings, morning energy on a 1-10 scale, mood at four checkpoints, water intake by the glass, steps, exercise minutes, calories, macros, screen time by app, deep work hours, shallow work hours, reading pages, meditation minutes, journaling words, and social interaction quality. The tracking itself takes forty minutes a day — twenty in the morning filling in yesterday's data, twenty at night logging the day. After three weeks you notice something: you are stressed about whether you tracked accurately, anxious when your numbers dip, and spending your deep work hours analyzing your deep work metrics instead of doing deep work. The monitoring has consumed the resource it was supposed to protect. You are not living a more examined life. You are living a more measured life, and the measurement is the main activity.

This concept is part of Phase 28 (Agent Monitoring) in the How to Think curriculum, which builds the epistemic infrastructure for agent monitoring.
