Often, a day is bad because you’ve fixated on things that went wrong. Stop, take a few deep breaths, and focus on how you feel, and where that feeling is in your body. Maybe it’s disappointment and your shoulders are sagging. Maybe it’s anxiety and your stomach is churning. Then take a few more breaths, and focus on which parts of your body feel OK. Now think about a few things that went right, even small ones. Maybe you got to class on time, or the fries at Lower hit the spot. Finally, think of a few small things that happened in the past week for which you’re grateful. If one of them was the result of something someone else did, reach out to them and thank them.
