The subtraction practice
Identify one thing to remove from your life today rather than one thing to add.
Key takeaways
- What it is: Identify one thing to remove from your life today rather than one thing to add.
- Why it works: Western self-improvement defaults to addition: more habits, more information, more goals. But cognitive load research shows that complexity in the environment and in the task-stack degrades decision quality, attention, and creative capacity. Deliberate subtraction — removing a commitment, a distraction, or a possession — reduces load and restores the state pu points at: uncluttered potential. This aligns directly with essentialism research showing that fewer, better-chosen pursuits produce more meaningful output.
- Evidence: Backed by observational / correlational evidence.
- Avoid: Adding a "subtraction practice" to the to-do list without ever actually removing anything. The practice counts only when something is actually gone.
Why it works
Western self-improvement defaults to addition: more habits, more information, more goals. But cognitive load research shows that complexity in the environment and in the task-stack degrades decision quality, attention, and creative capacity. Deliberate subtraction — removing a commitment, a distraction, or a possession — reduces load and restores the state pu points at: uncluttered potential. This aligns directly with essentialism research showing that fewer, better-chosen pursuits produce more meaningful output.
How to do it
- 1List five things currently claiming your time, attention, or space.
- 2Ask of each: "If I removed this, would my life or work be meaningfully worse?"
- 3Remove or defer at least one item that fails the test.
- 4Track for one week whether the removal creates the mental space you expected.
What the evidence says
ObservationalCognitive load research consistently shows that reducing task and environmental complexity improves decision quality and sustained attention. Essentialism — deliberate reduction to what matters most — has practitioner support and aligns with empirical work on choice overload.
Honest caveat: Research on subtraction is largely about task/choice reduction; applying it to life commitments broadly is a practitioner extension of the mechanism.

Common mistake
Adding a "subtraction practice" to the to-do list without ever actually removing anything. The practice counts only when something is actually gone.
IX Coach begins each planning conversation by asking what should be removed before asking what should be added, preserving pu as the default starting orientation.
