From a story on axios.com by Mike Allen, Erica Pandey, and Jim VandeHei headlined “The power of active gratitude”:

Whether we spend our time dwelling on things we’re grateful for or noodling on things that upset us matters.

The big picture: Shifting our attitudes to focus on giving thanks — not just during the holiday — has a direct link to our wellbeing.

Case in point: In one study, psychologists recruited a group of participants and asked half to take time weekly to write a few sentences about things they were grateful for from that week. The other half wrote about irritations or complaints.
