Think about how our thoughts will impact the listener BEFORE they come out of our mouth.
The listener hears no good of himself.
Everybody talks, nobody listens. Good listeners are as rare as white crows.
An intelligent person, looking out of his eyes and hearkening in his ears, with a smile on his face all the time, will get more true education than many another in a life of heroic vigils.
An appreciative listener is always stimulating.
All speech, written or spoken, is in a dead language until it finds a willing and prepared hearer.
