I enjoy using journaling prompts. I have a few that are my favorite that I reuse when I'm not feeling well or I need to shift my mood. One is:
List 20 things that make you smile. I thought we could do a similar thing and list 5 things that make us smile each day.
A sunrise
Watching my cats play
Eating a breakfast sandwich
Playing my game
Getting a text message
I would love to hear what makes you smile.
