12. Gratitude is a happiness booster
It has been proven that gratitude increases happiness, so be grateful for all the little things in life. In one study, participants were divided into 3 groups and one group was instructed to write about things that had happened during the week they were grateful for.
The second group wrote about things that had displeased them, and the third group wrote neither positively or negatively about events that had an effect on them. The participants who made gratitude notes were happier and more optimistic.
