In our modern society, opinions are actually considered to be a healthy thing, and it is true that they are not inherently unhealthy. The logical left brain thinks through taking sides and comparing. Problems occur when your dissatisfaction begins to identify with an opinion and turns it into a dogma. It is also at this point that another disease takes root inside you — the dis-ease of seriousness. The healthy expression of opinion is rooted in a certain playfulness that comes of having an equally developed right hemisphere of the brain. Whereas the left brain sees the parts, the right hemisphere only sees the whole.
