order to solve problems, it is helpful to first understand whether they are puzzle, obstacle, or entanglement. A puzzle need only be analyzed carefully: It is like unraveling a ball of yarn and requires patience more than anything else. An obstacle must be overcome: We must use force and perseverance to either destroy or move away from what is blocking us. An entanglement mires us in a maze of limitations: This most dangerous of situations requires that we use all our resources to extricate ourselves as quickly as possible.
