King Alfred the Great

“For in prosperity a man is often puffed up with pride, whereas tribulations chasten and humble him through suffering and sorrow. In the midst of prosperity the mind is elated, and in prosperity a man forgets himself; in hardship he is forced to reflect on himself, even though he be unwilling. In prosperity a man often destroys the good he has done; amidst difficulties he often repairs what he long since did in the way of wickedness.”
― King Alfred the Great
