How to get started
STEP 1
the phenomenon (3 minutes)
- Decision fatigue:
- - Mental exhaustion from making choices
- - Each decision depletes willpower
- - Quality of decisions deteriorates
- - Energy for learning reduced
- Research showed:
- - Judges more lenient early in day
- - Harsher decisions after many cases
- - Willpower functions like muscle
- - Gets tired with use
STEP 2
why IT happens (4 minutes)
- Willpower/self-control:
- - Limited daily resource
- - Shared across all decisions
- - Morning: full tank
- - Evening: depleted
- Brain uses glucose:
- - Decisions require energy
- - Prefrontal cortex (decision-making) is costly
- - Each choice burns mental fuel
- Decisions include:
- - What to wear
- - What to eat
- - What to study
- - When to take breaks
- - How to respond to distractions
- - Hundreds of micro-decisions daily
- By evening:
- - Willpower depleted
- - Harder to focus
- - Easier to procrastinate
- - Learning suffers
STEP 3
the solution (3 minutes)
- Reduce unnecessary decisions:
- - Plan night before
- - What to study tomorrow
- - When to start
- - Where to work
- - What materials needed
- - Morning routine
- Famous examples:
- - Steve Jobs: same outfit daily
- - Obama: only blue/gray suits
- - Zuckerberg: gray t-shirts
- - Why? Save willpower for important decisions
- Morning routine:
- - Automate breakfast
- - Lay out clothes
- - Pre-decide study time
- - No morning choices
- - Willpower preserved for learning
STEP 4
IMPLEMENTATION (2 minutes)
- Evening planning:
- - 10 minutes before bed
- - Tomorrow's schedule
- - Study materials ready
- - Remove morning decisions
- Result:
- - Wake with plan
- - No decision fatigue
- - Willpower intact
- - Better learning outcomes
- Extra boost:
- - Limit social media (infinite decisions)
- - Reduce choices during study
- - Take real breaks (not scrolling)
