I wish to lay very special stress upon the necessity at the beginning of the most expert and experienced instruction that is attainable. If circumstances make it impossible to give to the child the best all the time, then he should have the best at the start rather than later. Every effort and every sacrifice that are ever going to be made for the child's sake should be at the beginning of his school training, and not delayed till he is older. The years from five to eight or ten will determine his future success. If he has poor teaching during these early years, even the best teaching later will not be able to make up the loss entirely. But if he has good teaching during the first few years, then less expert teaching later cannot do him as much harm as it otherwise would. The early years are his most crucial period, and the best efforts should be expended then instead of when he is twelve or fourteen.
