Maintain positivity as a daily practice

Be pleasant, cheerful, and avoid criticism as a baseline — not only when things are good.

Why it works

Stafford’s research consistently found positivity — being generally pleasant, upbeat, and avoiding complaining — to be the maintenance behavior most strongly linked to satisfaction and commitment. The mechanism aligns with Gottman’s positive sentiment override: a positive relational baseline makes negative events less likely to be interpreted as threatening, and provides an emotional buffer that absorbs routine friction without it registering as relational damage.

How to do it

1. Notice your default tone with your partner in ordinary interactions — is it lighter or heavier than with others?
2. Make one deliberate positive bid per day that has no transactional function: a compliment, a joke, a shared moment.
3. When you have a complaint, surface it once clearly rather than letting it feed a pattern of low-level negativity.
4. Audit how often you greet your partner with a problem vs. a genuine positive acknowledgment.

Evidence

Across multiple studies, Stafford and colleagues found positivity to be the maintenance behavior most consistently and strongly associated with relationship satisfaction, commitment, and the sense that the relationship is worth maintaining. (observational)

This is observational/survey research; causality is plausible but not experimentally established. Positivity may reflect underlying satisfaction as much as produce it.

Common mistake

Reserving positivity for special occasions and treating ordinary interactions as neutral — the research suggests the ordinary is where most relationship quality is built or eroded.
