I started the day by doing something I really didn't want to do, but I did it and got it out of the way so it wouldn't be hanging over my head, preventing me from enjoying anything else. In our house, that known as doing the worst part first.
That expression came from my late father-in-law. When Sweetie was a kid and wanted to go to the sledding hill, his father loaded the kids in the car and gave them a choice... did they want him to drop them off at the top of the hill or the bottom... Did they want to do the worst part first, which would be climbing the hill. He would, of course, pick them up in the same spot they were dropped off, because it would have been too easy for them if he dropped them off at the top and picked them up at the bottom.
I did something similar as a kid. When I was served a plate a food, and there was something on it that I really liked, I would eat that last. Doing the worst part first is a a good rule to live by, and we're teaching it Pipsqueak. She does it more times than not now. Hopefully, it will prevent her from procrastinating when it comes to unpleasant tasks.
Do you do the worst part first?
