As a long time HN reader, I'm well acquainted with this article and every time I read it again, I'm reminded of these 2 famous sayings, which seem amusing in this context:

1. "Do as the priest says not as he does"

2. "It is far easier for me to teach twenty what were right to be done, than be one of the twenty to follow mine own teaching."

So now that you know what must be done, go out and do it, if you can. If not, teach it to others.
