2001 June 24, Martha Duffy, "Take This Job and Love It," Time:
  "I am a great believer in self-management, that you must survive and find a way to play the hand you are dealt."
2012 January 2, Alex Spillius, "Mitt Romney: a safe pair of hands?," The Telegraph (UK) (retrieved 9 April 2013):
  There were mainstream candidates who seemed stronger than Mr Romney. . . . But the party must play the hand it is dealt, which appears to be Mr Romney.
