I love this article on gratitude and one person's experience of writing down five things to be grateful for every day for a week. As mentioned in the piece, gratitude is a key component of a field of psychology called Positive Psychology. We don't often think of gratitude as something that can transform our lives. In fact, we may really only give it our attention at Thanksgiving. But cultivating gratitude has been shown to be one of the most effective ways to boost happiness and transform our lives in a meaningful way.
