Useful presidential take on learning
"Train them to virtue; habituate them to industry, activity, and spirit. Make them consider every vice as shameful and unmanly. Fire them with ambition to be useful. Make them disdain to be destitute of any ornamental knowledge or accomplishment. Fix their ambition upon great and solid objects, and their contempt upon little, frivolous, and useless ones."
John Adams (1735-1826), second US president and frequently absent father, advising his wife, Abigail, on how to educate their children, including future sixth president John Quincy.
