Tom Aspinall treats visualization as mental drilling: the psychological counterpart to repeating a physical technique. He writes simple statements about what he intends to do and how he wants to feel, keeps them somewhere visible, and rereads them. He also repeatedly imagines specific pressure moments, such as walking to the octagon, so that the physical event is preceded by many mental repetitions. The method does not predict every detail or guarantee an outcome. It aims to make the environment feel less novel, pair desired actions with a practiced emotional state, and reduce the gap between training and performance. Aspinall also rehearses enjoying the moment because he says he performs best when present rather than consumed by the final result.

Core principles

  • 01Train the mental side deliberately
  • 02Repeatedly imagined situations become more familiar
  • 03Rehearse the emotional experience as well as the action
  • 04Present-moment enjoyment can support performance

How to run it

  1. 1

    Define the pressure moment

    Choose one specific event or phase likely to create pressure, such as walking onstage or opening a presentation.

    Pro tip Rehearse a concrete scene rather than a vague ambition.

  2. 2

    Write the intended experience

    State what you will do and include how you want to experience it.

    Pro tip Keep the wording short enough to reread often.

    Watch out Do not treat the statement as a guarantee.

  3. 3

    Run detailed repetitions

    Imagine the surroundings, pressure, physical sensations, and your chosen response. Repeat the scene until it becomes familiar.

    Pro tip Include discomfort instead of imagining only effortless success.

    Watch out Mental rehearsal does not replace real practice.

  4. 4

    Use the rehearsal

    During the event, recognize familiar cues and return attention to the action in front of you.

    Pro tip Use enjoyment as an attentional cue if it helps you perform freely.

In the wild

A walkout rehearsed before fight night

Aspinall says that before he physically walks to the octagon, he has mentally walked out thousands of times. He imagines the environment and practices treating the moment as something to experience rather than escape.

The real walkout feels more familiar despite the pressure.

Illustrative board presentation

A founder writes that she will explain three decisions clearly and stay curious during questions. Each day she rehearses entering the room, seeing skeptical faces, pausing, and answering the first difficult question without rushing.

She enters with practiced responses to predictable pressure cues.

Common mistakes

Visualizing only the win

A perfect highlight reel does not rehearse the uncertainty and sensations that can disrupt performance.

Replacing practice with imagination

Mental repetitions support preparation; they do not create technical ability by themselves.

Is it for you?

Best for

People preparing for a consequential performance with a setting they can anticipate.

Not ideal for

Situations where visualization would replace the technical or physical preparation the task requires.

From the transcript

When I'm physically walking out mentally, I've walked out 10,000 times before I've actually physically walked out.

It's as simple as getting a piece of paper, writing down this week I will do this and enjoy it.
