Practice Makes Permanent
You can drive for 20 years without becoming a better driver.
Driving to work is repetition, not practice. You’re not isolating skills, you’re not getting feedback, you’re not working on what you can’t do yet. Your parallel parking hasn’t improved since week two because you’ve spent 20 years reinforcing what you already know.
Practice makes permanent, not perfect. You’re engraving the skill you have, not building new capability.
Practice that improves you is practice you’d rather avoid. The cellist doesn’t play through her favourite pieces—she drills the bars she stumbles over. The work lives just beyond current capability, with feedback that tells you when you’ve got it. A coach or clear metrics close the feedback loop. The cellist who spends 30 minutes drilling the bars she can’t quite nail will improve faster than the one who plays through pieces she can already perform.
Athletes use the same principle: they don’t scrimmage at match intensity every day. They drill specific movements—footwork, reaction time, technique—just beyond what they can comfortably do. The movement works or it doesn’t. You know immediately. Elite athletes train by isolating components, not running through the full performance.
The same structure appears in learning systems. Spaced repetition software surfaces the flashcards you get wrong. Master a card and it disappears for months. Fail one and it returns tomorrow. The algorithm forces you to drill weakness, not rehearse strength—same principle, different domain.
Twenty years of commuting doesn’t produce rally drivers because repetition isn’t practice. You’re maintaining a skill, not building one. The cellist drilling problem bars, the athlete isolating footwork, the flashcard algorithm surfacing failures—all share the same structure: discomfort, isolation, feedback.
The next time you catch yourself doing something you’re already good at, ask: am I practising, or am I just repeating?
