What is
VISION
Look into the future and define for your self what the change you want to see in the world will be.
about me
Your World
Your world could be anything. A collective of people, places, things and even nature or animals. It can be as small as your organization or as large as the the populous as a whole.
For example, a social media service like Facebook would make a vision that can enable the general population to move towards achieving their vision.
On the other hnad,
Why Does It Matter?
Defining and articulating the vision enables everyone in your world to get on the same page and move towards the common goal.
