Deliberate Practice
category
Deliberate practice, formalized by psychologist Anders Ericsson, is a specific form of skill development characterized by working at the edge of current ability, with immediate and accurate feedback on performance errors, and focused repetition of the precise sub-skills where weakness exists — as opposed to the comfortable repetition of already-mastered material that most people mistake for practice.
Role
Research on expert performance across domains — chess, music, sport, medicine, writing — consistently finds that the volume of deliberate practice, not raw talent or years of general experience, is the primary predictor of skill development. Most people practice in comfort zones, repeating what they already know, and then wonder why they plateau. The minority who understand deliberate practice and apply it systematically improve at rates that appear remarkable but are simply the predictable consequence of correctly structured effort.
