I fear that I will personally lose by the change. My mind does not always move straight ahead but backwards too. I distrust my present thoughts hardly less than my past ones and my second or third thoughts hardly less than my first. We are often as stupid when correcting ourselves as others… … I have long since grown old but not one inch wiser. ‘I’ now and ‘I’ then are certainly twain, but which ‘I’ was better? I know nothing about that. If we were always progressing towards improvement, to be old would be a beautiful thing.
~ Montaigne, The Complete Essays (1587-88)
