"You're going to spend the rest of your life in the future. Maybe we ought to think about this." - Daniel Burrus
A design futurist combines things from the past with current knowledge and adds the spark of his insights and hunches to create a specific vision of how the future will look.
You, the entrepreneur, a creator of ideas, combine existing things with current knowledge (problems, trends, technology), and by adding your unique insights, create a particular view of the future.
When you take your idea and implement it, you are designing the future—both your future and – hopefully – the future of the world.
