every kid is different. If the kid likes the plan and is willing to follow, it saves the parents time and trains the kid to be 'perfect' in parent's eye. Sounds a good plan! However, this is a schedule most adults can not strictly follow. It might put too much pressure on a kid, which might cause adverse effect on the kid's personality, such as looking for perfectness in this world, having high demand on other people and environment, ....The worst thing is if the kid can not follow sometimes, he might think he is not good enough and give up on himself and lose self esteem.
We need to have a goal, a plan to acheive the goal, and the determination and persistency to implement the plan.
It is important to have a reasonable goal, some challenge but not too much, for the age of the kid. It is important to let the kid know that if he can not follow exactly sometimes, it doesn't mean he is not a good kid. Everybody has weakness, we just need to try our best to do what we think we need to do. But if sometimes you really do not want to do, follow your heart to do what you like to do at the moment if it won't hurt other people and it won't destroy your life.
