Ask the Focusing Question

“What’s the ONE thing I can do such that by doing it everything else becomes easier or unnecessary?”

Why it works

A to-do list treats every task as roughly equal, but the value of efforts is wildly unequal — a few actions drive most results. The Focusing Question forces a ranking by asking not what you could do but what single action has the highest leverage, which combats the natural tendency to default to whatever is urgent, easy, or in front of you.

How to do it

1. Ask the full question for the area in question: "What’s the ONE thing I can do such that by doing it everything else becomes easier or unnecessary?"
2. Add a timeframe ("right now", "this week", "this quarter") to make it concrete.
3. Keep narrowing until you land on a single, specific, high-leverage action.

Evidence

Reflects the well-observed Pareto principle (a minority of inputs drive a majority of outputs) and prioritization research. The specific phrasing and "becomes easier or unnecessary" framing are Keller’s practitioner formulation rather than a tested instrument. (mechanistic)

Pareto-style imbalance is widely observed but not a precise law; the Focusing Question is a heuristic for finding leverage, not a guaranteed formula.

Common mistake

Producing a short list of "important" things instead of forcing it down to one, which defeats the purpose — the discipline is in the singular answer.
