A vision is a "thought" or "will" that is made up of very personal things, and there are as many thoughts as there are people. It should not be a simple brainstorming exercise to find the "right" vision. A vision that everyone could agree on would be a mundane vision that is not that interesting, to begin with. If we state a vision in the face of others, we will look for the right 'idea' and come up with only the most mundane goals. A vision is foreseeability that comes out of an individual's desire supported by concrete experiences to do this, no matter what people say, this is what we need to do. If you are a visionary person, you think your life like this. “My life is mine, so whatever life I choose to live, it is, in a sense, the right life!” That's what vision is all about, so if you want to find it, you have to find that thrusting thought from your experience of "I had to do". Although we are introducing a vision, you do not need to complete the vision making exercise within the two hours and you should continue searching the vision for you. Sometimes, it's good to stop for a moment and think about vision in your life.
Prof. Roberto Verganti explains the vision as the source of fascination for people, and it takes time to make such a vision in his book "Overcrowded". Sometimes we speak of a vision as a far-reaching challenge involving people from all over the world. Elon Musk's passion for the rocket business, for example, make people watching his new rocket launching show although you will neither buy the rocket nor use his service to go to Mars. Also, vision is an attitude and a desire to show a familiar world from a new angle. It is a motive that keeps several people looking in roughly the same direction, without necessarily indicating an exact destination. Prof. Verganti describes the process as deeping down the target point to which make us intuitively feeling ourself heading, within a horizontal vision of about 30-40 degrees below. You should gradually move under the surface of the water while repeating the process of conceptualising your vision and judging whether it is good or bad. If you just dig straight down vertically, you'll end up in the ditch. At first, the new vision is blurred and ambiguous. There is only a "sense of direction", but no clear idea of its value or significance. For others, of course, but even for oneself. Claude Monet mentioned the impressionism did not come under instantaneous inspiration but developed under a gradual sculptural process as the exchange of ideas amongst his fellows in Guerbois Cafe of Paris: "Nothing could be more interesting than these causeries with their perpetual clash of opinions. They kept our wits sharpened; they encouraged us with stores of enthusiasm that for weeks and weeks kept us up, until the final shaping of the idea was accomplished."
