President Obama often peppers his speeches with platitudes about how he and his administration "will not rest" until all hardworking Americans have jobs, health care reform is successful, the Department of Veterans Affairs is fixed, and so forth.
It's worth noting that the president has played a ton of golf, 183 rounds and counting, during his seemingly tireless administration. Predecessor George W. Bush logged 24 rounds through the first 34 months of his presidency, but he stopped in 2003 once the nation was at war.
National Review's Jim Geraghty compiled a full list of times Obama reverts "to his favorite trite form of reassurance," most recently in the condolence book for Dutch victims of the MH 17 tragedy, where he wrote, "We will not rest until we are certain that justice is done." Geraghty noted Obama then flew to the West Coast for three days of fundraising.
The president who says he won't rest has in fact becoming increasingly restless, frequenting civilian areas to connect with ordinary Americans and hosting long dinner parties with supposed intellectuals and friendly celebrities to free himself from the strains of office.
