Curiosity, willingness to take risks, and originality relate to each other too. Inventors are the most curious people. They look at something which for you and me would be a minor annoyance and use that problem as a springboard to an invention. People sometimes ask me how I find my layouts for calligraphy. I try things until I find something that works better than anything else I've found - and it's never the first thing that came to mind.
Imagination is the ability to visualize the solution to a problem.
Instead of the mystical notion we often have of it, creativity is really learning to use one's thinking skills. We associate creativity with childhood, because all children of normal intelligence possess it at birth. Obviously, in that frame of mind, little creativity will take place. Creativity is not just for artists. Consider the need for creative thinking in ministries.
