1. They go to parksOne study found that people who live in cities with more green space feel better than those surrounded by man-made materials. How much better? The happiness jump associated with green space is equal to about one-third the boost in well-being1 that people get from being married. In a similar vein2， another study found that a five-minute dose of nature improves self-esteem; green areas with water were found to be the most beneficial.2. They live in Scandinavian countriesOkay， so your place of residence may not be a habit so much as a circumstance， to the United Nations General Assembly's second World Happiness Report， Denmark is the happiest country， followed by Norway， Switzerland，， Sweden and Canada. Note that all of these are generally northern countries， what's the deal? See number 3.3. They practice 'hygge'Huh? Pronounced HYU-gah， Danes make it through their long dark winters with a healthy dose of this to maintain their position as the happiest place in the world. With no real equivalent in the English language， hygge is a cultural concept that revolves3 around intimacy4， gratitude5 and family; it's a kind of emotional coziness. As described by one Dane， "It's like a feeling， and it's big at Christmastime. The candles， the food， being with your family." But it lasts all year.4. They have satisfying jobs -- and if not， they quitIt's no surprise that workers who are happy with their work are happy with their lives. And in fact， about work were happiest in life， with 71 percent of them describing themselves as “thriving." And it's probably not that surprising that only 42 percent of poll respondents who said they were disconnected from their work described themselves as thriving. What's surprising is that 48 percent of those unemployed6 see themselves as thriving; that's 6 percent more than those with jobs; for many， being unemployed is happier than having a crummy job.5. They smell the flowersNo， this isn't an homage7 to the “stop and smell the roses” cliché; it's not about taking time for the delights in your life . It's about floral scents8 and the effect they have on mood. Much research has been conducted on how floral scents can influence behaviors. In one set of experiments， researchers found that a floral-scented room led to increased happiness and friendliness9. One researcher noted10 that the floral smell is an emotion manipulator and improves the mood. "The floral odors can make you happy; floral odors promote social interaction， social approach kinds of behaviors，" Haviland-Jones， of Rutgers University.6. They get dirty making mud pies. Medical researchers in the U.K. found evidence that “friendly” bacteria found in soil may activate11 the immune system， serotonin and help ward12 off depression.7. They exerciseWe know you didn't want to hear that， but fret13 not. The good news is that middle-aged14 women don't have to run marathons or go all-out for the emotional benefits of physical activity to kick in. And in fact， a study found that moderate intensity15 exercise — as opposed to intense exercise — more women to report later that they were in a better mood and to have greater feelings of energy， psychological well-being and "self-efficacy."8. They don't try to be … happy?Oops. Now that we've told you the secrets for happiness， we're here to dash your dreams. A prominent study shows that making happiness a personal goal will actually stand in the way of your achieving it. The researchers found that women who valued happiness more reported being less happy and more depressed16 than women who didn't place much importance on the goal."Wanting to be happy can make you less happy，" said study researcher Iris17 "If you explicitly18 on happiness， that appears to have a self-defeating quality."So if you really want to be happy， about it.
