QUOTE : In this I have entered, day by day, the number of pages I have written, so that if at any time I have slipped into idleness for a day or two, the record of that idleness has been there, staring me in the face, and demanding of me increased labour, so that the deficiency might be supplied,” he explained. “There has been the record before me, and a week passed with an insufficient number of pages has been a blister to my eye, and a month so disgraced would have been a sorrow to my heart.” A blister to my eye. You won’t find anything in the psychological literature summarizing so vividly the impact of monitoring.
