Abstract
Duckworth et al. show deliberate practice — studying and memorising alone — outpredicts other preparation activities for spelling-bee success; grit predicts choosing effortful practice.

Key findings
- Practice type matters — Deliberate practice beats being quizzed or reading for pleasure for competition outcomes — not all hours count equally.
- Grit mediation — Perseverance predicts selecting less enjoyable but more effective preparation — motivation shapes practice menu.
- Talent plateau — Early aptitude stops predicting rank once deliberate practice volume diverges.
- Solo effortful study — The winning activity is often solitary and effortful — social prep is not a substitute.
Limits
Single competitive domain (spelling bee) — generalize by mechanism, not by copying study hours. Does not replace Ericsson 1993 breadth.
When to open this
Open when Talent plateau stalls after aptitude carried early wins without error-focused reps.
Try this week: replace one passive review block with a solo rep that forces retrieval or error correction.
