3) Commit Conscious Acts of Kindness

Via The Happiness Advantage:

“A long line of empirical research, including one study of over 2,000 people, has shown that acts of altruism—giving to friends and strangers alike—decrease stress and strongly contribute to enhanced mental health.”

2) Find Something To Look Forward To

Via The Happiness Advantage:

“One study found that people who just thought about watching their favorite movie actually raised their endorphin levels by 27 percent. Often, the most enjoyable part of an activity is the anticipation. If you can’t take the time for a vacation right now, or even a night out with friends, put something on the calendar—even if it’s a month or a year down the road. Then whenever you need a boost of happiness, remind yourself about it.”

5) Exercise

Via The Happiness Advantage:

“After four months, all three groups experienced similar improvements in happiness. The very fact that exercise proved just as helpful as anti-depressants is remarkable, but the story doesn’t end here. The groups were then tested six months later to assess their relapse rate. Of those who had taken the medication alone, 38 percent had slipped back into depression. Those in the combination group were doing only slightly better, with a 31 percent relapse rate. The biggest shock, though, came from the exercise group: Their relapse rate was only 9 percent!”

I'm surprised that "appreciate something in your life" wasn't on this list.
