I just finished a book I was looking forward to reading but found disappointing none the less, Churchill on Leadership. It is on Winston Churchill and was supposed to be part biography and part leadership text. It kind of missed on both accounts.
But it did have a great quote regarding forgiveness. He spoke this when some people wanted him to bash Neville Chamberlin, a political opponent he just replaced as Prime Minister. These words were spoken in 1940.
"This (bashing Chamberlin) would be a foolish and pernicious process....Of this I am quite sure, that if we open a quarrel between the past and the present, we shall find we have lost the future."
