I too did this in 2016, for about 3-4 months. Mine was a single excel sheet, 30 minutes each. S for Sleeping, W for Work, D Drive, F Food eating & cooking, N for Bathing Cleaning etc, F for Fun, W for Time Waste. Simple conditional formatting. Last column counted the Ws Fs Ns & all. Next Sheet had some bar charts. My job was in Excel, so it was easy to log data. I used to use an A6 size simple printout to mark things. It was fun while it lasted, but I thought it was too much work. Now, as I learnt Google Apps Script, can use a simple HTML app, with GAS to easily log the hours or time slots.
