2. Boosts Personal Happiness
One of the unexpected outcomes of expressing gratitude can be that you get something back from it. This seems to be in line with research on the subject cited by Harvard Medical School, which involved participants writing about particular topics over the course of weeks.
During the study, one group wrote about things they were grateful for that had happened during the week, while another focused on things that made them upset. After 10-weeks, those who wrote about things they were grateful for “were more optimistic and felt better about their lives,” according to the source.
