From my experience, convincing others always implies that we find our way better than the others' way. But on the one hand, what is good for us might not be good for others, and on the other hand, if we have the freedom of doing things in our own way, we should acknowledge that others too have the freedom of doing it in their own way.
As you say, poeple don't like it all to be told what to do or not. No theory in the world helps them unless they had the corresponding practical lesson. We need to experience for ourselves. ;)
When we stop fearing for ourselves we stop fearing for others, realizing that we have all tools WITHIN to find "Home", with each one choosing when to resort to them ;)
