Apply the 80/20 principle to ongoing commitments

Identify the 20% of your commitments producing 80% of your results and protect them; cut or delegate the rest.

Why it works

The Pareto principle — a roughly power-law distribution where a minority of inputs generate the majority of outputs — applies to time commitments as well as revenue or effort. The lever is asymmetry: the top 20% of activities are often not just twice as good but an order of magnitude more valuable. Identifying and protecting them is higher leverage than improving the bottom 80%.

How to do it

1. List all your current standing commitments (roles, projects, relationships, recurring tasks).
2. Against each, estimate what percentage of your meaningful outcomes it generates.
3. Identify the top 20% by results — these are protected and given priority resourcing.
4. For the remaining 80%, evaluate: delegate, reduce, or eliminate. Set a 60-day deadline to make a decision on each.

Evidence

Power-law distributions (of which Pareto is one formulation) are empirically observed across many domains. Ferriss applies this as a heuristic for personal productivity. The 80/20 split is a rough rule of thumb, not a universal constant. (anecdotal)

The 80/20 ratio is a heuristic that may be 70/30 or 90/10 in any specific situation. It is a direction of thinking, not a precise measurement tool. Applied mechanically it can encourage eliminating necessary overhead that produces no direct output.

Common mistake

Confusing "generates the most revenue/results" with "most enjoyable" — the top 20% is sometimes difficult work you avoid, while the enjoyable 80% is what fills the day.
