It's very simple. At the end of every day, perhaps at the dinner table, you ask yourself or your family, what "went well today?" I can see how this would help. It's kind of a gratitude practice. I didn't have a great day yesterday when I read about this, and I was thinking/focusing on the parts that did not go well, but then I read this and started thinking about what had gone well. A piece of mail that I've been anxiously waiting for for 9 weeks, finally arrived yesterday. That was huge and in my mind, that detail was kind of buried in the stress until I took a second look at my day.
