Thanks for your response Jesse.  I look forward to reading that chapter.  All too often after the initial "big bang" roll out of the vision, attempts to keep the vision present amount to little more than periodic e-mails, presentations, and superficial artifacts like posters, mugs, etc. Keeping the vision alive requires finding ways to keep it front and center in everyday conversation - it takes discipline and often requires a shift in context on the part of positional leaders.  One of the shifts in context I think leaders need to make to "stay the course" is that they don't need to keep presenting the vision, they need to be in consistent conversation with people about the vision, what it means to people, how it is being manifested today, and its impact and implications for the future as they see it.
