First of all, I would say that part of what I was arguing is not that we can't have clarity, but that we need to understand the lessons we've learned from the past 15 years or so better, because it's not always the case that what we're doing is actually leading to the desirable results.
In terms of what I teach them, I can talk about the specifics of what we go through. I teach them first of all just to ask questions all the time so that they themselves understand that these are complex situations and complex environments.
