What a profound honor, privilege, & grace in this life, to be entrusted, even momentarily, with the temporary care, safety, and education of other peoples' children. "Education is not preparation for life; education is life itself." -John Dewey, "Education comes from within; you get it by struggle and effort and thought." -Napoleon Hill, "What nobler employment, or more valuable to the state, than that of the [individual] who instructs the rising generation." -Marcus Tullius Cicero, De Divinatione
