Write three lines each evening as a low-barrier reflection habit

Three lines per night — what happened, what you felt, what you want to carry forward — builds the reflection habit without the pressure of a full journal entry.

Why it works

Full journaling fails as a daily practice for most people because the activation energy is high: a blank page implies a lengthy entry. Three lines have minimal activation energy — anyone can write three lines. But the structure (event, emotion, intention) captures the three elements of reflective processing most reliably associated with learning from experience: encoding the event, labeling the affect, and setting a forward intention.

How to do it

1. Keep a dedicated small notebook and pen on the nightstand.
2. Each evening, write exactly three lines: what happened today (one fact), what you felt (one emotion), what you will carry forward (one intention).
3. Do not expand into a full entry unless you genuinely want to — the three-line structure is complete as is.
4. Do this for 21 days without evaluation; then read back the entries.

Evidence

Minimal viable journaling practices (brief, structured, recurring) are better maintained than aspirational ones; the three-element structure reflects the components of experiential learning cycles (event, reflection, generalization) in Kolb’s model. (anecdotal)

The three-line format is a practitioner design; the Kolb model describes learning cycle components, not specifically journaling. The connection is principled but not empirically validated for this format.

Common mistake

Skipping the evening entry on busy days and deciding the practice "doesn’t work for me" after three weeks — the entries on the hardest days are often the most revealing.
