The Model and teenagers

As I’ve learned more and more, I have wanted to share what I’ve learned with those I love the most. It’s a regular topic with my teenagers. They are patient, to their credit. But I find I’m the one doing all the talking and teaching and maybe even preaching. I think it would be more beneficial to them if we had a teenager-lead discussion, but I just have SO much to say and to share with them!
How could I teach these principles to my teenagers without doing the talking?
