Deliberate Practice

Deliberate practice

Experience does not produce expertise on its own; people plateau and stay there for years. Improvement comes from working at the edge of current ability on a specific weakness, with feedback tight enough to correct within the session.

Method

1. Target one specific weakness. Not the whole skill but the component you are worst at, since general practice reinforces what you already do.
2. Work just beyond current ability. Comfortable practice maintains; practice that fails part of the time is where adaptation happens.
3. Get feedback within the attempt, not afterwards. The tighter the loop between action and correction, the faster the improvement (see feedback-for-learning).
4. Repeat with correction, not just repetition. Repeating an error entrenches it, which is why unstructured practice can make you worse.
5. Keep sessions short and focused. Concentration at this intensity is limited, and an hour of real focus beats a distracted day.
6. Measure something objective. A number or an external judgement, since self-assessment of skill is unreliable at every level (see skill-assessment).
7. Return to fundamentals when stuck. Plateaus often trace to a basic component executed imprecisely (see mental-model-building).

Boundaries

Deliberate practice is effortful and cannot be sustained for long periods daily. It requires a way to know you were wrong, which some domains provide poorly. Domains without clear feedback need proxies and progress is correspondingly slower.
