The fact that the words individuals hear or read control the ways they think, feel, and act.

Human beings are directed by the words they hear or read, and also greatly influenced by the ways their parents, the members of their family, friends, neighbors, classmates behave, and by other role models, all of whom—intentionally or not—by example, intentionally or not, get others to do or not do the things they do. So, I am writing the lyrics to a song to word-direct as many people as possible.
