I am brand new at this leadership stuff. In my view, people need to be "voluntold". It's just like when you need someone to call 911 - you don't say, "Somebody call 911!" Instead, you point at a particular person and say, "You call 911!" Generic pleas for help often go unanswered because everyone assumes that someone else is going to step up. Put people on the spot. When you have your parents sitting there go up to a specific parent and ask them, "Will you take the YPT training this week?" Make them commit or shirk publicly. Go right down the row.
