The Happiness Project shows us how to change our life without actually changing our life, thanks to the findings of modern science, ancient history, and popular culture about happiness.

Gretchen Rubin realized one day that although she was working hard, it wasn't on the things that matter once the years have gone by.

As a result, she then decided to dedicate a year of her life to running happiness experiments, and The Happiness Project is the report of her results.

She tested ancient ideas about happiness and pored over the latest scientific research, as well as popular culture and common belief.

Her findings were a multitude of ways in which we can improve our happiness without having to make major life changes - like move to the other side of the world or make millions.

Happiness can be found in the everyday, and Rubin is here to prove it.
