Something I need to try to remember:

You can't wake people up through argument….

So how do you wake people up? My experience has taught me that you have to live what you believe. And you have to try very hard to crawl inside the others’ skin for a while, to feel what they feel, to see yourself the way they see you, to view life from their perspective, with their particular education, their particular experiences. It is only then that you may have any chance at all of getting a hearing from them.
After all, how many times have you had a life changing moment of realization as a result of an argument? Think about it.
