Son-9 gets some free video game time each day. After that, he has to earn it, to a maximum. I try to keep the list interesting and not too hard.
Today he cleared his stuff off the dining room table, and cleaned two shelves in his room. I explained he can get 15 minutes per shelf, or actual time spent, and pointed out that he’ll soon run out of fast shelves. (I don’t see any that will take over 10 — he’s quickly learning FlyLady’s “You can get a lot more done in 15 minutes than you think.”) He now does it without complaining, so he can reach 20 hours and unlock another character.
