The Pareto Principle: 80/20 Rule

80% of results often come from 20% of effort. Find your high-impact activities.

Vilfredo Pareto noticed 80% of Italy's wealth owned by 20% of people. This 80/20 rule appears everywhere: few inputs drive most outputs.

The Few That Matter

In most domains, a small fraction of efforts produces most results. Identifying and focusing on these high-impact activities transforms productivity.

Find the 20% that produces 80% of results.

Applying the Principle

• Audit time: What's actually moving needle?
• Focus high-impact: Double down on what works
• Eliminate low-impact: Stop things that don't matter
• Iterate: Refine based on results

Identify high-impact. Focus there. Ignore the rest.
