“Never let the things you can't do, stop you from doing what you can.”
Ronald Reagan (1911–2004) American politician, 40th president of the United States (in office from 1981 to 1989)
James Callaghan (1912–2005) Prime Minister of the United Kingdom; 1976-1979
Interview (2 May 1979), quoted in Michael Pilsworth, "Balanced Broadcasting", in David Butler and Dennis Kavanagh, The British General Election of 1979 (Macmillan, 1980), pp. 207-208.
Callaghan objects to the line of questioning of ITN's David Rose in an interview recorded on 2 May 1979. He was eventually persuaded to return and recorded a new interview, but owing to an agreement with NBC TV that they should have access to all material recorded by ITN, it was shown in the USA and then reported in the Daily Telegraph.
