How full of joy is your life?

How Gratitude Changes You and Your Brain
"Compared with the participants who wrote about negative experiences or only received counseling, those who wrote gratitude letters reported significantly better mental health four weeks and 12 weeks after their writing exercise ended. This suggests that gratitude writing can be beneficial not just for healthy, well-adjusted individuals, but also for those who struggle with mental health concerns. In fact, it seems, practicing gratitude on top of receiving psychological counseling carries greater benefits than counseling alone, even when that gratitude practice is brief." The authors also post HOW these changes might occur.
