Vision is easy. It's so easy to just point to the bleachers and say I'm going to hit one over there. What's hard is saying, OK, how do I do that? What are the specific programs, what are the commitments, what are the resources, what are the processes we need in play to go implement the vision, turn it into a working model that people follow every day in the enterprise. That's hard work.
