An example
Hafsa has not cooked since Eid. The kitchen has become a place she walks through quickly.
She picks one thing the night before, and it is not cooking a meal. It is chopping an onion. That is the whole plan.
Wednesday at six she does not want to. She does it anyway, badly, and it takes four minutes. She does not feel better afterwards, and she notes that honestly.
Thursday she chops an onion and puts it in a pan, because the pan was already out. Nobody planned that part. The second thing was cheaper than the first, which is the only result this lesson is asking for.
