I see that the root cause of most of humanities problems is a failure to communicate. We do not talk enough with one another, particularly about deep and/or personal things. The problem is not that we do not share our financial wealth; it is that we do not share HOW we got our financial wealth.
By developing and teaching good communication skills, the courage to be honest and most importantly the courageous compassion that it takes to truly listen to one another we can overcome this deficiency. When we recognize that we will not have the courage to be honest unless we have the courage to listen to feedback means that we first develop the skill of NOT beating ourselves up emotionally with our reactions to what people say to us or about us. It is hell to be afraid of ourselves and our reactions to what people say to us.
