The 3-tier decision cost taxonomy
Not all decisions cost the same cognitive load. The first move in budget management is categorizing your daily decision flow:
**Tier 1 — Routine decisions (cost: low).** What to eat for breakfast. Which Slack message to reply to first. Calendar review. These deplete the budget slightly per decision but you make many per day. Cumulative cost: substantial if uncontrolled.
**Tier 2 — Tactical decisions (cost: medium).** Today's priority order. How to respond to a moderately complex client email. Which task to delegate vs. do yourself. Per Roy Baumeister's research (summarized at Psychology Today), tactical decisions deplete the budget 3-5× faster than routine ones.
**Tier 3 — Strategic decisions (cost: high).** Pricing model changes. Hiring decisions. Product direction. Major client negotiations. These are the decisions where 30 minutes of pre-2pm thinking is worth 3 hours of post-3pm thinking. Per HBR's research on executive decision-making, strategic decision quality degrades faster than tactical when executive function is depleted.
