Learning about mental efficiency. As a survival mechanism, our body is always trying to find ways to conserve energy. In our physicality, movements, personality, thinking, relationships, society… etc. We put our energy in places, we get rewarded, returns energy and re-energizes us. Maybe it’s reading, working out, going to a party. Maybe it’s avoiding or putting in the bare minimum energy requirement in situations that our drains energy, is taxing or stressful, maybe things like thinking, social settings, work, etc.
