Is (are) the image an organization or individual has in mind for a desired future.

Vision is the image an organization or individual has in mind for a desired future. Vision should be distinguished from mission, which refers to the present situation, the today, the now. The vision, on the contrary, predicts a stage in the future. It is important to have a vision, whether you are an individual or an organization, since it provides you with a purpose and it gives you the focus and the enthusiasm to achieve it.
