Broaden your horizons
You know I find close-minded people very frustrating to deal with at times. You introduce them to an idea, or you float a thought and their only reaction is how can I use it, how can it benefit my immediate needs. Seriously. Broaden your horizons a little. Explore the thought. See the multitude of possibilities that thread can lead you, some not useful some useful, some producing dimensional changes if explored further. Don't switch your mind to pragmatism before you have had the chance to explore and play with an innovative approach. Because then you are just creating barriers and boundaries without understanding how big is the actual playground.
