Or, Why I Spent a Year Trying to Sing in the Morning, Clean My Closets, Fight Right, Read Aristotle, and Generally Have More Fun by Gretchen Rubin
In this lively and compelling account, Rubin chronicles her adventures during the twelve months she spent test-driving the wisdom of the ages, current scientific research, and lessons from popular culture about how to be happier. Among other things, she found that novelty and challenge are powerful sources of happiness; that money can help buy happiness, when spent wisely; that outer order contributes to inner calm; and that the very smallest of changes can make the biggest difference.
