When you most need to get happier, try giving happiness away.
In other words, you can’t make others happy unless and until you are happy yourself
The Atlantic in 2011, longitudinal studies of families show that one person’s unhappiness can be “poison” to others in close proximity. Wallace noted that women married to unhappy men tend to be unhealthier and live shorter lives than those married to happy men; children whose mothers have a happy marriage are 18 percentage points more likely to be happy at home than those with mothers in an unhappy marriage
Fortunately, research also shows that we have more control over how we affect others—and ourselves—than we might assume. The key is to act like a happy person would, even if you don’t feel like it.
