I think there is an ideal state for everything; static or dynamic. Some things are better if firm, unmoving and non-volatile, while some others are good when dynamic and ever changing. This thinking model is a special case of the yin yang model. Some examples: Examinations ( any filtering, screening, measuring, interviewing, appraisal... ) A stationery system of measurement is subject to gaming, If the objective is to get the best, and the variables of being best are many, then it makes sense to keep changing the screening patters every time. A stationery system will be gamed and if diamonds are what you are looking for any stone can be shaped to look like it given sufficient time. In the other direction things like fundamental principles or resolutions or the big goal of life need to be firmed up real soon.
