"Fish where the fish are" is a strategy principle: direct your effort, time, and resources towards the opportunities most likely to yield results. If you want to catch fish, go where the fish actually are — not where you hope they might be, not where it is convenient, not where you have always gone out of habit.
Applied to business, it means targeting the customers, markets, or channels most likely to buy. In personal productivity, it means focusing on the actions that produce the most value rather than staying busy on low-impact tasks.
The phrase became a staple of sales and marketing thinking in the mid-to-late 20th century. It captures a deceptively simple insight: most effort produces most results in a small number of places. The 80/20 principle — 80% of results come from 20% of effort — is the same idea in statistical form.
The phrase is often attributed to Willie Sutton, the American bank robber who, when asked why he robbed banks, allegedly replied: "Because that's where the money is." Whether Sutton actually said this is disputed — he denied it in his autobiography — but the logic is identical. Go where the value is concentrated.
Fishing is one of humanity's oldest activities, and fishing metaphors run deep through many languages. "A bad workman blames his tools" applies equally to a fisherman who blames the lake rather than his technique or location. The best fishermen know their water — they understand where fish feed, at what time, in what season. Knowing where the fish are is the foundational skill; everything else follows.
The phrase is useful because it cuts through complexity. In any situation where resources are limited — time, money, attention — the temptation is to spread effort evenly or to go where it feels comfortable. "Fish where the fish are" is a reminder that results come from concentration, not coverage. You cannot catch fish in an empty lake, however skilled you are or however long you wait.
Yes, it became particularly common in sales and marketing contexts in the 20th century. It advises focusing on the customers, channels, or markets most likely to produce results rather than spreading effort thinly.
The phrase has no single definitive author — it is a folk wisdom expression. It is often linked to the Willie Sutton quote ('That's where the money is'), which captures the same logic. It became widely used in business and strategy literature through the latter half of the 20th century.
