The One Thing — Gary Keller & Jay Papasan (Review)
The One Thing simplifies productivity into a single organising principle: focus on the most important task first, consistently.
Summary
The One Thing argues that extraordinary results come from narrowing focus to the single most important task — the one action that makes everything else easier or unnecessary. Keller and Papasan present a simple but powerful framework for cutting through distraction, prioritising with precision, and creating momentum through consistent, high-leverage effort. Blending productivity research with real-world examples, the book offers a clear blueprint for achieving meaningful long-term success.
