Turning inward helps me to see the good in my surroundings. The older woman on the adult tricycle who doubled back because she thought I might need help (I didn't, but still). The small acts of others that show me there is still a bit of humanity in humans. And also, all the beauty in nature and even man-made constructs like cities. It's a restorative process.
I like Jamie's idea of not saying anything online that I wouldn't say in real life. In my case, however, that's still not much editing when I'm angry enough. LOL
