# Energy Manager

## Overview

Time is fixed; energy fluctuates. Managing energy — physical, mental, emotional — determines what your hours are worth.

Everyone has rhythms: peak alertness, post-lunch trough, second wind. Fighting your biology with scheduling is a losing game.

Energy management = map your patterns, align demanding work to peaks, protect recovery, and fix the big drains (sleep, movement, food).

## When to use

- Afternoon crashes killing productivity despite 'enough time'
- Burnout symptoms while hours look reasonable
- Wanting sustainable high performance without overwork
- Designing a schedule around chronotype and energy
- Recovering from a period of chronic overwork

## Core concepts

- **Ultradian rhythms.**
  90-120 min cycles of alertness through the day. Work in focused sprints aligned to cycles; break between them. Fighting the cycle costs more than the break.
- **Chronotypes.**
  Morning larks peak early; night owls peak late. Most people peak mid-morning, trough after lunch. Know yours; schedule accordingly.
- **Energy audit.**
  Track energy (1-5) hourly for a week alongside activities. Patterns emerge: golden hours, drains, boosters. Data beats assumptions.
- **The big three.**
  Sleep (7-9h, consistent), movement (daily, especially walking), food (stable blood sugar). These dominate everything else combined.
- **Task-energy matching.**
  Peak -> deep creative work. Trough -> admin, email, errands. Second wind -> planning, lighter creative. Never invert this.
- **Recovery design.**
  Breaks, walks, naps (20 min), real lunch away from desk, evenings off, weekends off. Recovery is productive — it's when consolidation happens.
- **Energy drains.**
  Identify and fix: terrible sleep, back-to-back meetings, constant context-switching, unresolved conflict, decision fatigue. Drains first, hacks second.
- **Decision minimalism.**
  Decisions cost energy. Routines, defaults, and batching (clothes, meals, email) preserve willpower for what matters.

## Practical workflow

1. **Run an energy audit.**
   One week: hourly 1-5 energy + activity log. Find your peaks, troughs, drains, and boosters.
2. **Fix sleep first.**
   Consistent bedtime/wake, 7-9 hours, dark cool room, no screens 30-60 min before bed. Nothing else matters until this works.
3. **Add daily movement.**
   Walk daily (20-30 min minimum); exercise 3-5x/week. Movement is the highest-ROI energy intervention after sleep.
4. **Map tasks to energy.**
   Redesign the week: deep work in peaks, shallow in troughs, admin in slumps. Put it on the calendar.
5. **Design recovery.**
   Real breaks between sprints, lunch away from screens, 20-min nap option, hard stop time, one full day off weekly.
6. **Kill top drains.**
   From the audit: fix the 2-3 biggest drains (meeting overload? terrible chair? 5h sleep?). Drains before optimizations.
7. **Batch decisions.**
   Meal defaults, outfit routines, email windows, theme days. Fewer daily decisions = more energy for real ones.
8. **Review monthly.**
   Energy trends, sleep consistency, deep-work output. Adjust schedule seasonally — energy isn't static year-round.

## Common pitfalls

- **Time management only.**
  Perfect calendar, exhausted human. Energy is the multiplier on every hour — manage it first.
- **Ignoring sleep.**
  Optimizing productivity systems on 5-6 hours of sleep. Sleep debt makes every technique perform at 60%.
- **Caffeine masking.**
  Using stimulants to override troughs instead of scheduling around them. Works short-term, costs long-term.
- **No real breaks.**
  'Breaks' spent scrolling. Recovery requires actual disengagement — walk, stare out window, nap.
- **Peak hours for email.**
  Spending golden morning energy on inbox triage. Peak hours are for creation; inbox gets trough time.
- **Weekend catch-up myth.**
  Working weekends to 'get ahead' instead of recovering. Chronic under-recovery compounds into burnout.
- **One-size-fits-all advice.**
  5am routines for night owls. Chronotype is largely biological — work with it, not against it.
- **All optimization, no foundation.**
  Supplements and hacks while sleeping 6 hours and never moving. Foundations (sleep, movement, food) dwarf everything else.
