Stop Practicing the Wrong Thing First

Solène Achterberg is thirty-one, sitting in a glass-walled room on the fourteenth floor, waiting for a panel to decide whether she gets the senior role. Her résumé covers four industries in eight years. The person before her had spent all eight years in one. She is certain this counts against her. She is wrong.

The mechanism that makes early specialization feel safe is exactly what makes it limiting: you get very good at the questions one domain asks, and lose the ability to hear the questions it never thought to ask. Cognitive flexibility — the kind that lets you import a solution from one field into a completely different problem — is built by exposure to varied contexts, not by depth in one. The brain does not reward repetition with creativity. It rewards novelty with pattern recognition across wider distances. Specialists optimize. Generalists, early on, learn to see.

David Epstein documented this in Range, tracing how late-specializing athletes, scientists, and artists consistently outperformed early specialists in fields where the rules are not fixed and the terrain keeps changing. Which describes almost every modern knowledge job. The exception list is short: chess, classical music performance, certain surgical subspecialties. In those domains, early deliberate practice wins. Outside them, the data runs the other way. Most people are not training to be grandmasters. Most people are training for careers where the rules will change three times before they hit their peak.

You have sent in an application for a role that stretches across two departments, and you are trimming your cover letter to hide the breadth. You are apologizing, in careful professional language, for the very thing that makes you suited to it. Solène did not hide the four industries. She described what moved across them: the ability to read a room that had already made up its mind, and shift the frame before the decision landed. That is not a soft skill. It is the product of having been wrong in four different contexts and learned something different each time.

The career you are worried about building is not too scattered. It is still assembling its range. What feels like lost time is often the sampling period the research says you needed.
