This is similar to the previous point, aimed at your own behavior.
How many moral-values politicians and preachers have been busted for "walking the Appalachian Trail," as it were? Former South Carolina governor and family man Mark Sanford was once mentioned as a possible Republican presidential candidate before he took his alleged hike on that trail. In fact, he was traveling to Argentina to consort with his mistress. So much for that.
Don’t tell others of the importance of family as you destroy yours.
