My First Million

The best business ideas come from noticing what's working and doing it better, faster, or for a different audience.

Daily Behavior Virality Model

When you change someone's daily behavior, they talk about it continuously because people discuss what they're currently doing, creating sustained viral marketing

Decision Rule

Prioritize products and campaigns that change what people do every day rather than one-time purchases

How It Works

People recommend books while reading them, talk about daily routines they're doing now, and evangelize current behaviors more than past experiences

Failure Modes

Trying to create completely new behaviors vs. modifying existing ones

Daily behaviors that don't create visible social proof

Making daily behavior too complex to maintain

Not connecting daily behavior to ongoing product purchase

Example Decision

Bulletproof Coffee succeeded by modifying existing coffee drinking behavior rather than creating new supplement category, generating daily word-of-mouth as people discussed their morning routine
