The line "Uneasy lies the head that wears a crown." comes from which play of Shakespeare?

The phrase "Uneasy lies the head that wears a crown." comes from the play "King Henry the Fourth, Part Two" by William Shakespeare. This particular line from Act III, Scene I has been defined by literary critics to mean that a person who has great responsibilities, such as a king, is constantly worried and therefore will not get a good night's sleep.

In the world today, some psychiatrists and corporate headhunters have applied this phrase to business executives. It is noted that executives must handle a lot of major issues, rule/lead the business agenda, and as required be the difference between success and failure. So their brain is often heavy in thought, trying to find the best way to ensure that all agendas, mandates, and goals are successful. The individuals at this level of the corporate structure always seem to be constantly worried about something or someone.

To put it in simple words, an interpretation of Shakespeare's line would be that a king faced the liability of losing his head at the hands of a usurper. Top business executives in the 21st century who fail face the fact that they will lose their jobs and all of the power, prestige, and salary of being a company president, chief executive officer (CEO), top boss, etc.
