Maintaing a diary

Sir, A Criminal case under 498A was lodged against me in 2016. When things sarted going wrong from 2014, I consulted the law officer of my department. He adviced me to maintain a regular diary of events. The diary is that of my Department. In the diary , I divided each date into morning, afternoon and evening. I recorded each event both at home and office. I recorded the dates on which I had quarrel with my wife. I also wrote down the content of the quarrel. Kindly guide me what else to record in the diary. Shyamal
