When a teacher tries to teach something to the entire class at the same time, chances are, one-third of the kids already know it; one-third will get it; and the remaining third won’t. So two-thirds of the children are wasting their time.

Each of us must come to care about everyone else's children. We must recognize that the welfare of our children and grandchildren is intimately linked to the welfare of all other people's children. After all, when one of our children needs lifesaving surgery, someone else's child will perform it. If one of our children is threatened or harmed by violence, someone else's child will be responsible for the violent act. The good life for our own children can be secured only if a good life is also secured for all other people's children.

As you consider whether to move a child into formal academic training, remember that we want our children to do more than just learn how to read and write; we want them to learn in such a way that they become lifelong readers and writers. If we push our children to start learning these skills too far ahead of their own spontaneous interest and their capacity, we may sacrifice the long-range goal of having them enjoy such pursuits.
