What can we learn from a Rhino?

I have a little folder in my desk where I put hard copies of articles that are particularly thoughtful, significant, or otherwise. I usually put about 2 or 3 articles a year in there…quality–not quantity. I’ve got articles from Harvard Business Review (dating back to the 1960s) and BusinessWeek. I have saved articles from espn.com and GQ…and articles from Christian thinkers.
I’m going to add this one today: The Rhino Principle by Paul Johnson, British historian. It appeared in Forbes this month.
