Constructive Criticism: A Handbook Speaking & Listening More Effectively in Personal Relations, Groups, & Political Activities By Vicki Legion (Gracie Lyons), 1976
Constructive Criticism is a wonderful example of the blending of valuable and powerful socialist theory with a practical, down-to-earth pragmatism. The result is an extremely useful manual for people who work together for positive social change. Putting Gracie Lyon's suggestions into practice will increase the power of people's work as well as their personal sense of well being and satisfaction.

For conciseness I’ll write how this relates to the OP as a reply comment.
Books like Constructive Criticism are exactly what is necessary for those who want to build. How can communists have any credibility or authority to speak on societal change, if they cannot work out how to change themselves? By improving our selves as individuals, with conscious intentionality as described in Theses on Feuerbach, we demonstrate that concrete alternative I alluded to in the previous comment. The point of this development is not for moral high ground, but to shatter the distinction between the theoretical and the practical.
