Quite a unique concept, this article brings to the forefront, the idea of using simple cues for emotional regulation of oneself and others around us. I do believe that these can go a long way in ensuring day-to-day mental well being. The skills required include those such as active listening, which is simple to learn and requires a high amount of self consciousness to ensure that the person feels heard, without giving advice.

Do share your thoughts on why you think this might be important, and if it is something that can be taught as a skill in various settings?
