Rewire: A Practical Course in Adult Neuroplasticity

One habit rebuilt on purpose, the way the adult brain actually changes.

Shape: 5 steps, 21 days
Pace: About two steps a week
Each step: ~20 min + one action
Who it's for: Anyone who has tried willpower and would like a mechanism instead.

About this program

This course is built on a single, well-evidenced idea: the adult brain rebuilds itself in response to what you repeat. Over five short lessons you'll move from the biology of a neural pathway to a concrete weekly practice you can keep. Every lesson pairs an everyday analogy with the underlying science, then hands you something to do. No login, no cost — the whole course is free to read.

How each step works

01 · Learn

The mechanism, in plain language — what's actually happening in the brain and why it matters.

02 · Action

One concrete thing to do before the next step. Small enough to start today.

03 · Check-in

Questions to answer honestly, so you know whether it worked for you and not just in the study.

The steps

01The path across the lawnUnderstand what a neural pathway actually is, and why repetition — not intensity — is what builds it.

02Why the first week is the hardestRecognise the resistance of early repetitions as a signal of progress, and design around it.

03Consistency beats intensityLearn why frequent small repetitions rewire more reliably than rare intense effort.

04Unlearning: fading the old pathUnderstand why old habits fade rather than vanish, and how to let a disused path grow over.

05Your weekly rewiring practiceAssemble everything into a simple, repeatable weekly practice you can keep for the long term.
