Your brain likes to rely on patterns and methods you have developed that have worked for you in the past. This is normal. Your brain likes to keep things inside a comfort zone that does not require significant investment of energy. New patterns or solutions require large amounts of energy and focus and usually require large blocks of time.
Back to the quote from earlier – “We have no model for this!”
If that’s true, consider this. A model (a prediction or decision-making pattern) is only as good as the value received by using it. If old models and patterns are not producing good results but are still being applied, there is huge potential for waste and risk!
