I call it “Vitamin N.” It is the word children need to hear most, but it is currently the word children hear least. It is arguably the most character-building word in the English language, but then helping children achieve great things (or creating the illusion that they are achieving great things) has eclipsed helping children build strong character. That is unfortunate indeed because high achievement alone does not produce solid character, but a person with solid character will always do his or her best.
