Provebs of the Trail

A few years ago while walking the Australian outback, I learned an old Chinese proverb from a Canadian I met on a walkabout. The proverb goes something like this: A gem is not polished without rubbing... [the second half I have since forgotten]. I really think some politicians, and those in professions not enlightened through travel, should listen to the lessons of others, the lessons of travel, and the lessons of ancient cultures.
