If the earth is man's extended body, to be loved and respected as one's own body, those who do no greening of themselves will hardly bring about the greening of America. The idea of 'greening' involves color, flowering, freshness of spring, and, above all, respect for what is organic and vegetative as distinct from the mechanical and metallic.
Nothing is more limiting than a closed circle of acquaintanceship where every avenue of conversation has been explored and social exchanges are fixed in a known routine.
Old friends pass away, new friends appear. It is just like the days. An old day passes, a new day arrives. The important thing is to make it meaningful: a meaningful friend - or a meaningful day.
If two friends ask you to judge a dispute, don't accept, because you will lose one friend; on the other hand, if two strangers come with the same request, accept because you will gain one friend.
