Unreviewed — agent-drafted
This card was drafted by a software agent. It quotes nothing from the work itself; everything below is a description written for this catalogue, and the bibliographic details were checked against a public catalogue on the date shown.
We recommend it whenever effort feels high and progress feels flat: the usual cause is a target with no feedback attached, and this is the book that names that.
Ericsson ran the studies the popular ten-thousand-hours claim was drawn from, and spends part of this book correcting what was made of them. Reading the researcher's own account is the cheapest way to see how far a real finding travelled from its evidence.
What separates practice that changes performance from repetition: a well-defined target just beyond current reach, full attention, immediate feedback that names the error, and a teacher or a proxy for one. Also his idea of mental representations — the structures that let an expert see a pattern where a beginner sees pieces.
Two things to try
- Pick one skill and define today's target as something you cannot yet do reliably, small enough to attempt twenty times in a sitting.
- Find your feedback source before you start — a test, a recording, a person. Practice without one mostly rehearses the error.
- After a session, write the specific thing you got wrong and why. If you cannot name it, the target was too big.
Level, and what it means here
This text assumes you have met the vocabulary before, usually from one of the beginner items here. It is a description of the book, not of you.
