We always study a lot on how to manage big organizations, but seldom think how we can better manage our family life. I would say, better management of family life is more crucial to any society than managing big organizations, because, right organizations will evolve and sustain only in places where families are better managed. Therefore think, learn and practice better management of family life for a calm and pleasant life for all.
Practice it and make it a habit. Then the nature will make it sustainable by triggering necessary genetic engineering!
