Conclusion
The conclusion emphasizes that lasting results come from continuous, small improvements, which compound over time like the Sorites Paradox. The chapter reiterates the importance of systems over goals and the Four Laws of Behavior Change (make it obvious, attractive, easy, and satisfying) as a framework for building good habits and breaking bad ones. The secret to success is consistently refining these systems for marginal gains.
Key Stories & Examples
Sorites Paradox
The ancient Greek parable of the Sorites Paradox asks when adding one more coin turns a poor person into a rich person, to illustrate the cumulative impact of small actions. Adding one coin will not make an impact, but continuing to add coins will eventually have an impact.
Small, seemingly insignificant actions, when repeated consistently, compound to create significant results over time.
