Cultivating a “What is best for our community” mindset

We have evolved into a culture wherein the most important emphasis is upon satisfying our individual needs. So often our song is mostly only one note: me me me me ... what is best for me. There are still some cultures today wherein the first problem solving thought is “what is best for the whole, our community, our life support systems, i.e. Creation ... we are all interconnected." How do we begin the shift that will bring this thought pattern into our ego-centric minds when faced with decisions before us.
