Three good things (positive emotions pillar)
Write down three good things that happened today and why they happened.
Key takeaways
- What it is: Write down three good things that happened today and why they happened.
- Why it works: Negativity bias causes the brain to register negative events more vividly than positive ones. The three-good-things exercise counteracts this by requiring deliberate attention to positive events and their causes. The causal attribution step ("why did this happen?") is critical: attributing positive events to internal, stable, global causes builds learned optimism, which has downstream effects on motivation and resilience.
- Evidence: Backed by randomized trials / meta-analyses.
- Avoid: Doing it perfunctorily ("had coffee, it was fine") — the mechanism requires genuine attention and the causal attribution step. Without the "why," it reduces to a gratitude list without the attribution benefit.
Why it works
Negativity bias causes the brain to register negative events more vividly than positive ones. The three-good-things exercise counteracts this by requiring deliberate attention to positive events and their causes. The causal attribution step ("why did this happen?") is critical: attributing positive events to internal, stable, global causes builds learned optimism, which has downstream effects on motivation and resilience.
How to do it
- 1Each evening, write down three specific good things that happened today — large or small.
- 2For each, write one sentence about why it happened (your role in it, a person who contributed, a circumstance that enabled it).
- 3Be specific: "Had a good conversation with Sam about the project" is more useful than "had a good day."
- 4Continue for at least two weeks; effects build with consistency.
What the evidence says
RCT / meta-analysisSeligman et al. (2005) found three-good-things to be among the most effective positive psychology exercises in a randomized trial, with happiness increases and depression decreases persisting at six months.
Honest caveat: Effect sizes are modest; the study used a self-selected internet sample. Replication with more rigorous methods shows smaller effects, though still positive.

Common mistake
Doing it perfunctorily ("had coffee, it was fine") — the mechanism requires genuine attention and the causal attribution step. Without the "why," it reduces to a gratitude list without the attribution benefit.
