Ask: What’s your first step? And then what will you do? What will keep you from doing that? How can I help? Who else can help? What will you do differently next time?
Listen without judgment: I know very well that little duck that is quacking in your head that says “that’s the wrong way” and “that will never work”. When he starts in, take a couple of deep breaths and remind yourself that you are listening, not judging.
