The Happiness Project

Gretchen Rubin · 2009

Experiment within the life you already have.

Big Idea

Rubin’s memoir explores whether deliberate changes in ordinary habits can make an existing life feel more satisfying.

A year of experiments

Monthly themes turn a broad wish for happiness into practices that can be tried and examined.

Everyday energy

Ordinary routines and neglected tasks become part of the project instead of waiting for dramatic reinvention.

Relationships

The experiment examines how daily behavior affects the people closest to Rubin.

Personal interests

Activities need to fit the person rather than someone else’s picture of an impressive life.

Resolutions

Tracking an action makes it easier to see whether an intention is becoming a habit.

Khizooo Take

Choose an experiment in your own circumstances instead of copying every detail of another person’s memoir.

  • Book ideas for reflection, not individualized medical or mental-health treatment.

Remember

A useful experiment can start inside an ordinary day.
