How each edition is put together

Every edition follows the same modular structure. Any section can be switched off for a given month and the letter still reads as intended.

Small changes, measured in years

This month: why consistency beats intensity, and one habit worth keeping.

Sample edition · January 2026

TemplateThis is an editable sample edition. All text marked [DEMO] is placeholder copy and contains no real products, claims or statistics.

A note to open

[DEMO TEXT — replace] In clinic, the question I hear most often is which single change matters most. The honest answer is that no single change carries the day. What tends to matter is the change a person can still be doing in a year's time.

[DEMO TEXT — replace] This edition looks at that idea from three angles: what the evidence generally supports, one habit worth building this month, and a common belief worth re-examining.

This month

[DEMO] Consistency as a clinical variable

[DEMO TEXT — replace with the month's feature.] Prevention is rarely dramatic. It is a set of ordinary decisions repeated often enough to shift a trajectory, and its effects are usually invisible until the point at which they matter.

[DEMO TEXT — replace.] The practical implication is that a plan you can sustain through a busy month is generally more useful than an ideal plan you abandon in the second week.

Read the latest insights

Reading, watching, thinking about

  • Reading

    [DEMO — replace with what you are actually reading this month.]

  • Watching

    [DEMO — replace: a talk, documentary or lecture worth the time.]

  • Thinking about

    [DEMO — replace: an open question from clinic or research you keep returning to.]

One thing to try this month

[DEMO] Anchor a fixed wake time, seven days a week.

  • [DEMO] Choose a wake time you can keep on a difficult day, not an ideal one.
  • [DEMO] Keep it within about an hour on weekends.
  • [DEMO] Get outdoor light early in the day where your schedule allows.

[DEMO TEXT — replace.] A stable wake time is one of the simpler levers people have over sleep regularity, and it usually costs nothing.

Worth a second look

Often said

[DEMO] “Strength training is only relevant later in life.”

More accurately

[DEMO] Muscle and strength are generally easier to build and maintain the earlier the habit starts.

[DEMO TEXT — replace with a careful, non-absolute explanation. Avoid statistics unless you can cite them.]

From the writing desk

[DEMO — optional, keep short.] A brief line on the literary work, when there is something genuine to share. This block is meant to stay small.
