A slideshow illustrating a dozen research-tested happiness activities you can start practicing today.
Sonja Lyubomirsky’s book The How of Happiness offers readers more than a dozen everyday activities they can practice to become happier in the short and long term. Lyubomirsky compiled the list of activities after conducting and reviewing years of research about what distinguishes happy from unhappy people.
The slideshow below features some of the main activities Lyubomirsky and her colleagues have identified that make people happier. You can read the full list below the slideshow; click on the links next to some of the activities for instructions (created by Lyubomirsky’s lab) on how to practice them.
To help you decide which of these activities might be right for you, read about how Lyubomirsky and graduate student Kristin Layous have been exploring the best ways to practice some of these activities and why some of these activities may work for some people but not others.
For more on these activities, also see Jason Marsh’s article on “The Hows of Happiness” and download our “Six Habits of Happiness” poster.

Savor life’s joys. Pay close attention to life’s momentary pleasures and wonders through thinking, writing, or drawing, or by sharing them with others.
