Practice means designed work with feedback — Ericsson’s construct, not Gladwell’s hour ticket.
Where Macnamara et al. 2014 published domain bands (games ~26%, music ~21%, sports ~18%, education ~4%), this page uses those rounded figures and does not invent new precision.
Steps
- Drop the slogan
Strike 10,000 from the plan.
Gladwell is not a syllabus.
- Pick one failure
A measurable miss.
Weakness first.
- Write the drill
Ten minutes that target it.
Design on paper.
- Record one attempt
Audio, video, or written solution.
Feedback object.
- Adjust once
Change one parameter.
Not a full restart.
- Stop while attending
End the block before collapse.
Quality minutes only.
Checklist
- Target named — Not “get better”.
- Task slightly too hard — Comfort is a warning light.
- Feedback in the hour — Not next month.
- Minutes honest — Solitary ≠ ensemble ≠ scrolling.
- Teacher or proxy — Someone designed this.
- Rest scheduled — Attention is a resource.
- Domain band recalled — Music is not education’s 4%.
- Residual humility — Practice is minority variance in the 2014 coding.
Drills
- Slow-to-fast loop — Music and sport: under-tempo until errors die, then raise.
- Error collection — Write the last five misses. Tomorrow’s hour starts there.
- Interleaved set — Mix problem types so the diary cannot hide in one familiar pattern.
- Teach-back — Explain the move to a peer. Gaps become audible.
- Blind replay — Cover the score or the notes and reconstruct. Retrieval is a feedback form.
Pitfalls
- Hour worship — The slogan replaced the construct.
- Teacher-less grind — Repetition without design is the thing Ericsson contrasted against.
- Ignoring residuals — Macnamara’s bands are not an insult to practice; they are a size estimate.
- Importing conservatoire hours into homework — The education variance band is a caution.
Tools
- Metronome and recorder — Oldest cheap feedback pair in music.
- Video at 120 fps — Sport’s diary.
- Spaced-repetition software — For factual sub-skills that sit under a craft.
- A human teacher — Still the main designer in most domains Ericsson studied.
Deliberate practice: design the hour; retire the poster. Education is not a diagnosis.
