“There is no education like adversity”

“There is no education like adversity” was written by Benjamin Disraeli, 1st Earl of Beaconsfield (1804-1881) in Endymion (1880). William Hazlitt (1778-1830), in the essay “On the Conversation of Lords” (1826), had much earlier written something similar:
 
“Prosperity is a great teacher; adversity is a greater. Possession pampers the mind; privation trains and strengthens it.’”
 
People who have an education from adversity are said to have gone to the “college/school/university of hard knocks.”

“You have good judgment, great industry, a fairly quick perception, little passion — perhaps hardly enough; but that is probably the consequence of the sorrows and troubles of early life. But, after all, there is no education like adversity.”

Handy-book of Literary Curiosities

Pg. 17:
Carlyle admits that “adversity is sometime hard upon a man, but,” he adds, “for one man who can stand prosperity, there are a hundred that will stand adversity” (Heroes and Hero-Worship” The Hero as Man of Letters). Hazlitt had already said the same thing in his “Sketches and Essays.” “Prosperity is a great teacher; adversity is a greater” (On the Conversation of Lords). And the arch-plagiarist Disraeli, in “Endymion,” ch. lxi., gives us the aphorism, “There is no education like adversity.”
