Nigel has come up with a concept of a Glass Wall, and it really struck a chord with me. You are expending a lot of energy to reach a goal. You can see your goal clearly, and you can see how to get there - its only a few steps away. After a disproportionate amount of time and effort, you find yourself in a totally unintended place, and with no real idea why. You haven't achieved your goal, but you've expended all the time and energy you have available for that task. When someone asks you why you haven't just taken the few simple steps to reach your intended destination, you find that you can't answer. Its those Glass Walls. But what puts those Glass Walls in the way? Is is the Malignant Requirement and the Headless Chicken ganging up on you?
