The Mindsponge culture can be defined as a set of thinking processes, beliefs, and behaviors that is result- or target-driven. It is an entrepreneurship culture that urges me to overcome hardship with a transparent mind about my target. Adopting this culture is a tough process, but its fruitful results are worth the cost. Especially in the next decades, humanities have to acquire two crucial targets for sustainable development: curbing climate change and reducing biodiversity loss. To accomplish these targets, shifting the eco-deficit mindset to the eco-surplus mindset at the individual level and building eco-surplus culture at the organization level (e.g., business sectors) are required. Obtaining the Mindsponge culture can help us progress and actualize these objectives through creative performance.
