I used to play Dungeons & Dragons, and realized that the attributes you assign each character is also helpful for self-improvement:
I work on improving these attributes, and that’s essentially what self-improvement is all about. D&D’s alignment system is interesting to contemplate, too, as it relates to ethics and morals.
We’re all role-playing to some degree. How much or how little we do it isn’t as important as how comfortable we are in the roles we play. I now have a better understanding of my character.
