The right to do something does not mean that doing it is right

William Lewis Safire (December 17, 1929 – September 27, 2009) was an American author, columnist, journalist and presidential speechwriter.

He was perhaps best known for the NYT column, On Language (popular etymology).  His fare well article ‘How to Read a Column’ should be a must read for every high school senior.  And, all adults.

Don't fall for the "snapper" device. To give an aimless harangue the illusion of shapeliness, some of us begin with a historical allusion or revealing anecdote, then wander around for 600 words before concluding by harking back to an event or quotation in the opening graph. This stylistic circularity gives the reader a snappy sense of completion when the pundit has not figured out his argument's conclusion.

Never assume the obvious is true

Last, but not least, avoid clichés like the plague
