This concept is revolutionary in a society that conditions us to "not change who we are" for other people. Only in unhealthy extremes does this apply, otherwise, such a concept is death to any and every human relationship. Change, especially for others, is the essence of selfless love. Love is allowing eachother to shape our character, adopting the belief that we cannot become who we want to be without surrendering the "I" to the "we". Parents, sports teams, successful business modules, etc.
