"You parents naturally know how to relate to each of your children and to help them learn. Your biggest problem is that so many of you are afraid that teachers or society or somebody out there will frown on your way of teaching. You feel safer if you stick closely to a book or series of books, because that is somebody else's plan, that is in print, that must be right.
For some children and for some of the time, certain books will happen to be just right. But if you find yourself struggling to mold your child to a book, try reversing priorities. It's the child you are teaching, not the book. Bend the book, or find another; make the studies fit the child."
