Charlie Munger's 5 Thinking Models for Smarter Decision-Making:

1. Inversion
Think about the problem from the opposite direction.
• Ask: "What could cause failure?"
• Make a "Things I Will Not Do" list
• First, avoid mistakes
2. Second-Order Thinking
See beyond the obvious.
• Ask: "And then what?"
• Anticipate ripple effects
• Consider long-term impacts
3. Circle of Competence
Stick to your expertise.
• Be clear about what you know (and what you don't)
• Focus on your strengths
• Expand carefully through learning
4. Opportunity Cost
Every choice has a price.
• Each "yes" = a "no" elsewhere
• Time and energy are limited
• Weigh trade-offs before acting
5. Small Progress, Big Impact
• Improve by 1% each day
• Habits compound over years
• Tiny wins = huge results
