One simple truth, so many ways of saying it. Here are a some you may recognize and others you may not:

• “Keep your eye clear, and hit ’em where they ain’t” said the baseball legend William Keeler.
• “The purple cow”, a book written by Seth Godin of “Permission Marketing” fame.
• “Zag when others zig”, the famous adage turned into a book by Marty Neumeier.
• “It don’t mean a thing (If it ain’t got that swing)” is a 1931 composition by Duke Ellington, with lyrics by Irving Mills.
• “The beginning of greatness is to be different and the beginning of failure is to be orthodox” is a famous quote by David Ogilvy.
• “If I am going to sing like somebody else, I don’t need to sing at all” Billie Holiday
