Log energy (1-5) three times daily with sleep, meals…

Why This Is a Rule

Energy availability is your most variable cognitive resource — it fluctuates based on dozens of upstream factors (sleep quality, nutrition timing, exercise, emotional state, social interactions, time of day, day of week). Most people have intuitive theories about what drives their energy ("I'm a morning person" / "exercise gives me energy"), but these theories are often wrong because memory biases overweight dramatic episodes and underweight subtle patterns (When energy data contradicts your narrative about what…).

The two-week data collection protocol captures enough data points (42 energy readings with concurrent upstream factors) for pattern detection to identify your actual energy predictors — which may differ significantly from your narrative predictions. The three-times-daily frequency captures the within-day energy curve (morning, afternoon, evening), and the concurrent factor logging (sleep, meals, exercise, emotional state) provides the independent variables for correlation analysis.

AI pattern detection excels here because humans can't easily identify multivariate correlations across 42+ data points. "Your energy is best on days when you slept 7+ hours AND exercised before noon AND had no difficult conversations before the measurement" is a three-variable interaction that intuition can't detect but pattern analysis can.

When This Fires

• When you want to optimize energy allocation but don't know your actual energy predictors
• Before designing energy-aware scheduling (Annotate time blocks with required energy state…) — you need the data first
• When energy feels unpredictable and you want to identify the controllable upstream factors
• Complements When feedback is slower than behavior frequency, the brain… (temporal credit assignment for delayed feedback) with the energy-specific data collection

Common Failure Mode

Intuition-based energy theory: "I know I'm an afternoon person." Maybe — or maybe your "afternoon energy" correlates with the specific lunch you eat on days you feel good in the afternoon. Without data, you're optimizing on narrative rather than pattern.

The Protocol

(1) For two weeks, log three times daily (morning, midday, evening): Energy: 1-5 scale (1=depleted, 5=peak). Sleep: hours last night, quality 1-5. Meals: what and when (last meal before measurement). Exercise: type and duration today. Emotional state: 1-5 (1=distressed, 5=thriving), brief note on dominant emotion. (2) Keep logging simple — 30 seconds per entry. Use a spreadsheet, app, or simple note. (3) After two weeks: analyze (or feed to AI): which upstream factors most strongly predict high-energy readings? Which predict low-energy readings? (4) Use the findings to design energy-aware scheduling (Annotate time blocks with required energy state…): schedule high-demand tasks during conditions that predict high energy.
