Not so much teaching, but still a lot of preaching.

And that's not meant as a put down - there's nothing wrong with sharing your vision of how things are and how they could be better and might get worse. It's always been part of how we communicate with each other, and it's always been part of the traditions.

"If you don't know where you're going, it doesn't matter which way you go" - and "If you don't care what you're saying, it doesn't much matter how you say it."
