“A fundamental aspect of flexibility is what psychologists call pathways thinking, and it’s the ability to find or create many workable paths to a given outcome.10 The more flexible you are as a person, the more willing you’ll be to try multiple approaches to getting where you want to go. The more rigid you are, the more dogmatically you’ll try forcing the same approach even when it proves unsuccessful. As Einstein is credited with saying: “The definition of insanity is doing the same thing over and over again, but expecting different results.”
