Portnoy describes simplification as an iterative subtraction mentality rather than a single cleanup. He first reduced consulting work by not replacing contracts as they ended, then unsubscribed from newsletters, stopped watching television, and became more selective about meals and meetings. Months later, the same lens exposed deeper layers. The decision rule Melissa gave him was to look for things that were no longer serving him or making him happy, whether a job, habit, or relationship, and remove them. The intended mechanism is to peel away accumulated layers that obscure a more peaceful baseline. The practice also requires tolerating stillness: space is not immediately proof that another activity should fill it. Repeated reviews allow simplification to move from surface clutter toward structural commitments.

Origin

Melissa taught Portnoy to simplify and subtract after he left Palantir and kept recreating busyness through consulting and Silicon Valley meetings.

Core principles

  • 01Simplification happens in layers rather than one purge
  • 02Peace can emerge by removing what obscures it
  • 03A commitment should justify itself by continuing to serve
  • 04Subtraction creates space for stillness and better-fitting choices

How to run it

  1. 1

    Inventory the layers

    Review recurring work, media, meetings, habits, and relationships that occupy time and attention.

    Pro tip Start with commitments that repeat automatically.

    Watch out Do not confuse every demanding responsibility with a non-serving one.

  2. 2

    Apply the service test

    Ask whether each item still serves you or contributes meaningfully to the life you are trying to build.

    Pro tip Notice obligations maintained mainly as a badge of busyness or importance.

    Watch out Short-term discomfort does not automatically mean something lacks value.

  3. 3

    Stop replenishing

    Let low-value commitments end and decline to replace them with equivalent work or noise.

    Pro tip Non-renewal is often easier than an abrupt purge.

    Watch out Check contractual, financial, and family consequences before ending a commitment.

  4. 4

    Remove recurring noise

    Unsubscribe, stop, or reduce one repeated input or activity that failed the service test.

    Pro tip Choose recurring removals because their benefit compounds.

    Watch out Do not replace one form of automatic consumption with another.

  5. 5

    Protect the space

    Allow more stillness and observe what becomes easier to feel or notice before adding anything new.

    Pro tip Treat initial emptiness as part of the practice.

    Watch out Seek support if stillness exposes distress you cannot safely manage alone.

  6. 6

    Peel the next layer

    Repeat the review after enough time has passed to notice subtler commitments that were previously hidden.

    Pro tip Ask what you no longer need to be doing now.

    Watch out Endless subtraction without a positive direction can become avoidance.

In the wild

Busyness after Palantir

After leaving Palantir, Portnoy feared he might not get another job and filled his time with consulting. He let those engagements expire without replacing them, unsubscribed from newsletters, stopped watching television, and reduced the breakfast, lunch, and dinner meetings he had treated as a sign of importance.

Successive removals created more stillness and began a deeper simplification process.

Common mistakes

Refilling the space immediately

Replacing each removed obligation prevents stillness from revealing the next useful change.

Treating subtraction as one cleanup

Portnoy describes new layers becoming visible only after earlier simplification has settled.

Dropping necessary responsibilities

A difficult obligation may still serve an essential purpose and requires a different response than deletion.

Is it for you?

Best for

People who are overcommitted, transitioning, or trying to rebuild a calmer and more intentional life.

Not ideal for

People using simplification to abandon essential responsibilities or avoid difficult but necessary work.
