I succeeded in doing all 17 tasks that I set myself yesterday, though it took me longer than I expected and it was late and I was tired by the time I finished. Instead of learning the lesson, I went mad today and set myself 38 points - and of course failed ignominiously. So 17 points yesterday and 0 today.
The moral of this is that the game should be used only for those things which you want to give priority to getting done - certainly the total shouldn’t be in double figures. You can and will of course do many things which aren’t on the list.
