Fernandes describes learning from a father who could recognise a strong performance while immediately pointing to the moments that remained below his son's potential. The reusable mechanism is a two-part review: first acknowledge the result, then inspect the remaining margin rather than declaring the work finished. External criticism becomes an input, not an instruction. Fernandes says he looks back at his game and changes only what actually needs improvement. This preserves ambition without requiring every criticism to be accepted. The method works best when the remaining margin is specific and actionable: a decision, execution error, or preparation gap that can be tested next time. It becomes counterproductive if the review erases success, demands perfection in every domain, or prevents necessary recovery.

Origin

Fernandes says his father would notice the bad moments even after a two- or three-goal performance. He connects that upbringing with his present habit of reviewing criticism for useful changes rather than letting it alter his identity or effort.

Core principles

  • 01A strong result can be celebrated without being treated as perfect.
  • 02Specific criticism can reveal the next useful improvement.
  • 03Feedback should change behaviour only after it survives review.
  • 04Small remaining margins still matter when standards are high.

How to run it

  1. 1

    Recognise the result

    State what worked and why it was valuable. Do not make improvement dependent on pretending the whole performance was poor.

    Pro tip Name one outcome and one behaviour worth repeating.

    Watch out Skipping recognition can turn a useful review into permanent dissatisfaction.

  2. 2

    Locate the margin

    Find the small part that fell short of the available standard. Make it a specific moment, choice, or execution gap.

    Pro tip Ask what the missing two percent actually consisted of.

    Watch out Do not use an abstract demand for perfection as evidence.

  3. 3

    Inspect the evidence

    Review the performance and test whether the criticism is accurate. Separate a useful observation from opinion, distortion, or noise.

    Pro tip Use footage, work samples, or measurable outcomes where possible.

    Watch out High-profile criticism is not automatically correct.

  4. 4

    Choose one adjustment

    Translate the valid margin into one behaviour to practise or decision to change. Keep the next test narrow enough to observe.

    Pro tip Define what the adjustment will look like in the next attempt.

    Watch out Changing everything at once makes the lesson impossible to isolate.

  5. 5

    Retest without erasing progress

    Apply the adjustment and compare the next performance with the last one. Preserve what already worked while testing the new behaviour.

    Pro tip Review the same evidence point after the next attempt.

    Watch out Continuous improvement still requires rest and proportion.

In the wild

A strong game with room left

Fernandes recalls that his father could watch him score two or three goals and still identify the bad moments. The result remained good, but it was not used to hide decisions or actions that could improve.

Fernandes says he learned to tolerate criticism and inspect his own game for changes.

Reviewing a successful presentation

A manager celebrates winning approval for a proposal, then reviews the one question the team answered poorly. They preserve the winning structure, rehearse a clearer answer, and test it in the next meeting.

A good result becomes a base for one evidence-led improvement rather than a reason to stop learning.

Common mistakes

Turning every win into a failure

The method starts by recognising the result; it does not redefine anything short of perfection as worthless.

Accepting criticism without checking

Fernandes says he reviews his game to see whether change is needed rather than treating every comment as true.

Chasing vague improvement

A remaining margin must become a specific adjustment that can be tested.

Is it for you?

Best for

People reviewing strong but improvable performances in sport, work, study, or craft.

Not ideal for

Situations where relentless optimisation is damaging recovery, wellbeing, or the ability to recognise genuine success.
