Have you heard this term before? It was coined by Stephen Covey and the concept is a belief that there are ample resources and success to share with others. Contrasting to Scarcity mindset, this kind of thinking focuses on bringing win-win solutions and nurtures in an environment where there is a sense of high self-worth and security in individuals.
I find we can extend this to organizations as well. Win-win solutions don’t come as a co-incidence, but as a consequence of conscious thinking.
