Minimum viable version of the behavior

Reduce the new behavior to the smallest unit that still tests the hypothesis.

Why it works

Activation energy — the effort required to start — is the most common failure point in behavior change, not lack of willpower once started. Shrinking a behavior to its minimum viable form reduces the energy barrier. It also isolates the real variable being tested: whether the behavior fits your life, rather than whether you have the stamina to sustain a demanding version of it.

How to do it

1. State the full behavior you want, then ask: "What is the smallest version that still tests whether this works for me?"
2. Commit to that smaller version for the trial period rather than the full version.
3. Only scale up after a minimum viable version has run successfully at least once.

Evidence

Consistent with research on activation energy and friction: reducing the cost to initiate a behavior significantly improves follow-through rates. Bandwidth research shows that cognitive and motivational resources are limited, so simpler designs succeed more reliably. (mechanistic)

Most friction-reduction research tests environmental design, not cognitive reframing of task size; the principle extends plausibly but the exact "minimum viable" framing is practitioner guidance.

Common mistake

Choosing a minimum version so trivial it answers nothing ("think about exercising"), rather than a genuinely reduced version that still tests whether the behavior is feasible in your actual life.
