Gretchen Rubin's Happiness Manifesto.

A Happiness Manifesto

• To be happy, you need to consider feeling good, feeling bad, and feeling right, in an atmosphere of growth.
• One of the best ways to make yourself happy is to make other people happy; One of the best ways to make other people happy is to be happy yourself.
• The days are long, but the years are short.
• You're not happy unless you think you're happy.
• Your body matters.
• Happiness is other people.
• Think about yourself so you can forget yourself.
• "It is easy to be heavy: hard to be light."—G. K. Chesterton
• What's fun for other people may not be fun for you, and vice versa.
• Best is good, better is best.
• Outer order contributes to inner calm.
• Happiness comes not from having more, not from having less, but from wanting what you have.
• You can choose what you do, but you can't choose what you like to do.
• "There is no duty we so much underrate as the duty of being happy." —Robert Louis Stevenson
• You manage what you measure.
