Perfect for you if...

You're juggling too many priorities and suspect most of your effort goes nowhere.
You want practical, actionable advice that doesn't require overhauling your entire life.
You've read self-help books before and appreciate frameworks that actually clarify thinking rather than inspire vague change.

Maybe not for you if...

You need a single, comprehensive read rather than bite-sized daily wisdom.
You're sceptical of productivity advice and prefer living without systems.
You're looking for emotional support or deep psychological insight, not efficiency principles.

About this book

80/20 Daily is Richard Koch's day-by-day guide to applying the 80/20 principle to everyday life. The book provides a year's worth of daily insights designed to help readers identify the 20% of activities in their lives that produce the most significant results, so they can focus on doing more of what works best. The core concept explores how a small proportion of time generates most results, how fewer than 10 decisions in life are truly important, and how four key factors influence happiness more than anything else. The guide teaches readers to recognize activities with a high ratio of results to effort, enabling them to achieve success as they define it while minimizing unnecessary effort.
