Gratitude Letter — 15 min

The Gratitude Letter is a 15-minute weekly practice: write a 300-word letter to someone whose specific action made a difference to you, one of the most replicated positive-psychology interventions. Delivering it amplifies the effect, though just writing it still moves mood meaningfully.

The practice

Once a week, write a 300-word letter to someone whose specific action made a difference to you. Delivering the letter amplifies the effect; just writing it still moves mood meaningfully.

Where it fits in a day

  • Once a week: the practice is weekly, not daily — pick a consistent slot.
  • When you have a clear 15 minutes: enough time to write the full 300 words unhurried.
  • Before or after delivering it: delivery amplifies the effect, so plan to send it where you can.

Why it works

  • Writing the letter still moves mood meaningfully on its own.
  • Delivering it to the person amplifies the effect.
  • It is one of the most replicated positive-psychology interventions.
