The gratitude visit

Write and deliver a letter of thanks, in person, to someone you never properly thanked.

Why it works

Gratitude is amplified when it’s expressed and witnessed rather than just felt privately. Composing a specific letter forces you to articulate exactly what the person did and why it mattered, and delivering it in person creates a shared emotional event that strengthens the relationship. The combination of expression and connection is what makes the effect unusually large.

How to do it

1. Choose someone who helped you whom you never adequately thanked.
2. Write a concrete letter naming what they did and the difference it made.
3. Read it to them in person if you can, rather than emailing it.

Evidence

In Seligman’s randomized intervention study, the gratitude visit produced the largest short-term boost in happiness and drop in depressive symptoms of the exercises tested, though that particular boost was relatively short-lived. (rct)

The strongest effect was immediate and faded over weeks; it’s a powerful one-off more than a daily habit.

Common mistake

Sending a quick text or generic "thanks for everything" — the power comes from specificity and in-person delivery, both of which a shortcut removes.
