Smile more often

In a study in which they were observed, test participants who described themselves as happy also behaved happily: they smiled more often, were more playful, and appeared more amiable. They expressed criticism less often, spoke less about guilt, and seemed less irritated or anxious. This means: If people say that they are happy, this can obviously be observed in their behavior. A total of 50 people provided information about their feelings of happiness and were observed during the short interviews.
