We need to be in the open mode when pondering a problem — but! — once we come up with a solution, we must then switch to the closed mode to implement it. Because once we’ve made a decision, we are efficient only if we go through with it decisively, undistracted by doubts about its correctness.
— John Cleese

Great Innovators Think Laterally

"The creative process is just that: a process. Recognizing value that others have missed doesn’t require preternatural clairvoyance. A well-honed creative process enables us to intuitively recognize patterns and use those insights to make inductive predictions about divergent ideas, both vertically within categories, and horizontally across categories. By understanding the genealogy of innovation within a given category, we can imagine what might come next."
