Episode notes
Identity Drives Behavior
- Willpower predicts academic and professional success better than IQ, charisma, or wealth.
- Identity shapes behavior so seeing yourself as the kind of person you want to be changes actions.
From Fast Food To Health Identity
- Derek used reading about diet and future projection to change from nightly fast food to a health-focused identity.
- He imagined his ideal future self and then chose behaviors congruent with that identity.
Say 'I've Decided' Not 'I Believe'
- Use decisive language: say "I've decided I am..." instead of "I believe I am..." to create commitment.
- Then list evidence of that identity to reinforce it through actions.
