I am always pausing briefly during my sim sessions to make my son endless cups of coffee (yes, I spoil him :# :D ), wash a few dishes while I wait for my kettle to boil, start prepping a meal, or set a load of laundry so I don't bother about making sure everything is done before I start. Having said that, I guess I do have a kind of ritual.
1. Check the forum. Although the forum is deathly quiet of late and there's very little to read/respond to, I still like to check before I go offline to play.
2. Start loading my latest save.
3. My game takes about 5 minutes to load so I take advantage of that time to make a cup of coffee/tea and go to the bathroom whether I need it or not ;)
