The best business ideas come from noticing what's working and doing it better, faster, or for a different audience.
Useful vs True Belief Framework
Prioritize whether a belief is useful to hold over whether it's objectively true, since beliefs influence behavior and outcomes.
Decision Rule
When evaluating what to believe, ask 'What behaviors will this belief create?' rather than just 'Is this true?'
How It Works
Beliefs shape actions, actions shape results. Sometimes believing something positive (like 'I'm lucky') creates better outcomes regardless of objective truth.
Failure Modes
Believing useful but false things that create long-term harm
Ignoring important truths because they're uncomfortable
Using this as excuse for wishful thinking
Applying this to areas where accuracy is critical (engineering, medicine)
Example Decision
“Choosing to believe you're a 'lucky person' because it makes you take more chances and notice opportunities, even if luck isn't objectively real.”
