The purpose of this article is multifactorial. The primary question we investigate here refers to human barriers and established practices in a local county that obstructs pathways towards a sustainable future, as well as the measures taken to overcome difficulties and their societal impact. We base our analysis solely on the experience gained during the 2012-2015 planning period for the sustainable development of Vytina county-Greece. Our research focuses on sustainable development and its dependence on local community behaviours, as well as alternative ways for citizen involvement in the development process in order to avoid obstacles encountered in established bottom-up methodologies. Societal constraints include the complexity of communications and relationships between residents, the community's existing internal processes, a complex external environment, and a lack of shared vision which all contribute to the ego of the inhabitants, and to their time availability. These constraints represent obstacles and threats. The fundamentals of the planning process should neutralize and override these obstacles. It is important to recognize and measure these constraints and evaluate their societal impact. Weak predictions/estimates, inconsistent goals, top-down policy decisions, short-sighted planning, resistance to change, and intractable local government can all be barriers to bottom-up methodologies. The bottom-up process, fair and meaningful, is somewhat cumbersome and requires time to mature in order for sustainability practices to be effective. But the pilot application can help foster alternative approaches that allow the citizen to enter the era of sustainability easier and faster. The prerequisite is the existence of a rich cultural heritage. Facing all these problems in the planning for the sustainable development of a local community today, I wonder how a sustainable outer space civilization can be accomplished in the distant future when we have finally arrived at, what Michio K aku refers to as, the God equation or theory of everything.
