The 80/20 Principle: The Secret to Achieving More with Less by Richard Koch explores the idea that 80% of results come from 20% of causes. This principle—also known as the Pareto Principle—can be applied to business, productivity, relationships, time management, and beyond.
80% of outcomes come from 20% of efforts.
The majority of what we achieve comes from a small fraction of what we do. The goal is to identify those few high-impact actions and focus on them.
A small number of inputs lead to the majority of outputs.
Most of what we do yields little to no real value.
Examples:
20% of products = 80% of profits
20% of customers = 80% of revenue
20% of tasks = 80% of progress
Identify the high-value 20%.
Eliminate, automate, or delegate the low-value 80%.
Don’t do more—do less, better.
Maximize return on time, energy, and resources.
Prioritize best-selling products or top clients.
Focus on tasks that drive real results.
Use to-do lists and planners to highlight the 20%.
Protect your most productive hours.
Cut low-impact meetings, emails, and chores.
Nurture the few connections that bring joy, energy, or growth.
"The key to success is not doing more. It’s doing less — but doing it better."
You don’t need more hours or more hustle. You need to find your top 20% and focus there.
Create an 80/20 worksheet to map out priorities.
Combine with Parkinson’s Law ("Work expands to fill the time available") for even greater efficiency.
Use the 80/20 Principle to work smarter, not harder.
