Nobody cares about your idea. - Inverted Passion

The central thesis is brutal but accurate: users won't change their behavior to accommodate your product. The only valid reason someone adopts a new tool is if they're already exhibiting that behavior and your product makes them more than twice as efficient at something they care about. Not 10% better, not incrementally smoother - at least 2x better on a dimension that matters to them.

This cuts through all the startup mythology about revolutionary ideas and innovative solutions. Behavior change is incredibly difficult, and people simply don't restructure their habits for marginal benefits. You can have the most elegant solution in the world, but if it requires users to think differently or work differently without massive gains, it won't stick. The math is unforgiving: the friction of changing behavior costs more than small improvements deliver.

The practical implication is that product development needs to start with observation, not innovation. What are people already trying to do? What workarounds have they built? What pain is so acute that they're actively seeking alternatives? Your product should slot into existing behavior patterns and make them radically more efficient. If you're asking users to trust your vision and change how they work, you've already lost. They don't care about your vision - they care about their own productivity, their own goals, their own day-to-day reality.
