Today in Clear Creek's Leadership Development Program, we were blessed to have Will Mancini speak to us about Vision vs. Mission. Contrary to what I had understood, Mission is something that doesn't change. It's the overarching goal that you are always trying to acheive. Vision on the other hand, can change and should change in order to keep you focused on the mission. As an exercise for seeing how to cast Vision, we listened to the complete "I have a dream" speech from Martin Luther King Jr. and were asked to write down elements of the speech that were key parts of casting Vision.
Many of us may have heard the portions of the speech, but I'm completely convinced that all of us should listen to the whole thing - all 17 minutes of it. King paints an amazingly vivid picture with his spoken words. His tone and delivery transformed the written word into a speech that brought tears to my eyes and made me want to get up and take action - exactly what casting Vision is all about.
Do yourself a favor and listen to King's speech. You'll be better for it.
