get boy2 AGREE@target/consequence

This is a reasonable principle. Better than imposing target/penalty on boy. Would help build ownership, the holy grail.

This principle works best with self-confidence, but we don’t want to aim below the kid’s capabilities, like a piece of cake. It’s the adult’s job to figure out the 110% level as a challenging yet achievable target.

If above 150%, then boy would feel forced to agree. 曲打成招. Therefore, as a necessary condition, the adult has to observe boy’s reaction. If forced to agree, then we can’t count it as agreement.

The more buy-in, the easier to enforce. For a 5-minute serious effort, parents need 5 minutes persuasion/wrestling to get the buy-in. Then boy will spend 30 wall-clock  minutes.
