Does this sound like the set of challenges you might be facing?

  • I can do it perfectly at my own desk in my usual setup, but the second I have to do it somewhere else
  • I can nail this skill perfectly in the one familiar setup I practiced in, but the moment anything about the situation changes I’m lost
  • I drill the exact same problem over and over until I can do it in my sleep, but the moment it shows up looking even a little different I freeze
  • I finish all my reps of one skill before I touch the next, so when they show up jumbled together in real life I freeze
  • I cram everything into one long marathon session and walk away feeling like I’ve nailed it, then a few days later it’s mostly gone

Practices that may help

  1. Contextual Interference: Why Varied Practice Beats Blocked Repetition
    Contextual interference is the performance disruption that occurs when practice conditions are varied or interleaved rather than blocked. Robert Bjork and colleagues showed that despite producing lower performance during acquisition, high-contextual-interference practice (varied, interleaved) consistently produces better retention and transfer on delayed tests than low-interference blocked practice. The difficulty is the mechanism, not the obstacle.
  2. Practice the same skill in different physical and social contexts
    Vary the environment, time of day, or social setting of your practice so the skill is not bound to a single context.

  3. Introduce variability once basic schemas are formed
    Vary the surface features of problems once the deep structure is learned to build transferable knowledge.

  4. Add the difficulty of varied practice
    Change the context, examples, and conditions instead of drilling identical reps.

  5. Interleave practice across different skill types within a single session
    Mix practice across multiple distinct skills in a session rather than completing all repetitions of one skill before moving to another.

  6. Distribute practice sessions across days rather than massing them
    Four 30-minute sessions across a week produce more durable skill than one 2-hour session, even at equal total time.

  7. Calibrate practice difficulty so it is challenging but not overwhelming
    Aim for 60–85% success rates in practice — not perfection, and not near-failure.

  8. Switch to a new variation before mastering the current one
    Move to a different variation or task before you feel fully comfortable — the premature switch is what drives deeper encoding.

  9. Mix topics during retrieval practice rather than blocking by subject
    When reviewing material from multiple topics, alternate between them rather than finishing one before moving to the next.

  10. Schedule random practice for retention goals, blocked practice only for initial acquisition
    Use blocked repetition to learn a new movement or concept, then immediately shift to random practice once the basics are present.
