The Happiness Project

Gretchen Rubin · 2009

A year-long DIY experiment in becoming happier — with what already works.

Summary

Rubin spent a year systematically applying happiness research to her own life: a different theme each month (energy, marriage, work, parenthood, money) with concrete resolutions and a tracking chart. The book isn't about overhauling life; it's about being incrementally happier inside the one you already have. Her honesty about what worked, what didn't, and where good intentions broke down makes it unusually grounded for the genre.
