“Santos looks at the work of Sonja Lyubomirsky, a psychologist at the University of California, Riverside, and the author of The How of Happiness. Lyubomirsky is well known for her thought experiment about what affects our happiness, which she expresses in a pie chart: She proposes that roughly 50 percent of happiness is determined by genes (i.e., totally out of your control), roughly 10 percent is determined by circumstance (i.e., somewhat out of your control), and the final 40 percent is determined by your thoughts, actions, and attitudes (i.e., entirely within your control)…
…there are certain habits that have been shown to be consistent among happy people. Happy people devote time to family and friends. They practice gratitude. They practice optimism. They are physically active. They “savor life’s pleasures and try to live in the present moment…”

It’s pointed to in the article, but it’s probably worth highlighting Penn’s Authentic Happiness website.
