To be influenced by emotions and imaginations, is a desirable characteristic of human brain. He can be considered an animal who remains satisfied with whatever situation he is thrown in, and does not feel a need to visualize rosy pictures of a glorious future. Wit or wisdom, in fact is a refined form of vision only.
If you intend to start a business, your imagination will create a mental picture of your successful business with all minute details like: the benefits to be derived, places where customers are located, where to find the cheapest raw materials and best time to buy and store it, seasonal patterns of high and low sales volumes, etc. Thus, the entire business plan is visualized before starting the actual activity. With proper decision making skills and little refining based on experience, this mere imagination can be made into a grand successful project. But a mind without such imagination will keep on toiling hard in the rut of life, nothing more than that.
