Seven hundred hours. That's what Félix Ondoua logged on language-learning apps before his first real job interview in French. He failed it inside four minutes. Not stumbling — blank. The words he'd tapped and sorted and matched on a glowing screen simply did not arrive when a stranger in a grey suit leaned forward and asked him something direct.
You don't practice a skill in the abstract and then deploy it in the specific — the brain stores them as different things. Repetition builds a retrieval path, but that path is indexed to context: the sounds around you, the stakes in your chest, the format of the demand. Train in a quiet room with unlimited time and that is precisely what you get good at. The real situation, with its friction and its pressure and its irreversibility, is a different room entirely. Transfer between them is weaker than almost anyone assumes.

”This is why Ben Hogan, whose deliberate practice of ball-striking is documented in his own writing, reportedly hit shots on the course that he had already played mentally in granular detail before stepping up. He was collapsing the distance between rehearsal and execution, not supplementing one with the other. The specific mechanics of what you do in practice have to match the specific mechanics of what performance actually demands. Approximations compound the gap.
If something recently went worse than your preparation suggested it should, the question worth sitting with isn't how much more to practice but in what form. Pull up the moment itself in memory. The actual conversation, the actual task, the actual room. And trace back to what you were doing when you were getting ready. Where did the format diverge? Most people find it fast: they rehearsed the content but not the delivery, the speech but not the interruption, the plan but not the constraint. Félix needed to have awkward real conversations months earlier, not better vocabulary scores.
Practice isn't preparation for the real thing. At sufficient resolution, it either is the real thing or it isn't preparing you for it.
