This goal has the following fine print specified by tjb:
The point is to get going. Of course, what the goal criteria describe is by no means the actual practising.
I am allowed to do the chores after the deadline - but only during episodes where I live "night shift" and as long as I don't procrastinate going to bed. That means, if I get up at 11am instead of 8am, the deadline shifts back by 11-8=3 hours.
