Grab your gripe. Inspect its type. Is it small enough to not need any way around it? Is it big enough to down your mood?
Bend the thought to see the good that's hiding in between the lines.
Road works ahead? A walk just might refresh your head.
Caught a flu? A break from work could revitalize you.
Stuck behind a slow chauffeur? Driving slow is less expensive.
Try your own as research has shown: bending the small affects almost all.
I tried to make a poem about an exercise I give to my patients. Because gripes add up to bring you down if you let them. Keep practicing and drive your attention to things you're thankful for.
