Bible quote: “A happy heart makes the face cheerful, but heartache crushes the spirit.”

“Some of you will be successful, and such will need but little philosophy to take them home in cheerful spirits; others will be disappointed, and will be in a less happy mood. To such, let it be said, “Lay it not too much to heart.” Let them adopt the maxim, “Better luck next time”; and then, by renewed exertion, make that better luck for themselves.”

Abraham Lincoln (1809–1865) 16th President of the United States

1850s, Address before the Wisconsin State Agricultural Society (1859)

“Happiness was useless to me. It was heartache that filled my purse. What happy man has need of Shakespeare?”

“What comfort there is in a cheerful spirit! how the heart leaps up to meet a sunshiny face, a merry tongue, an even temper, and a heart which either naturally, or, what is better, from conscientious principle, has learned to take all things on their bright side, believing that the Giver of life being all-perfect Love, the best offering we can make to Him is to enjoy to the full what He sends of good, and bear what He allows of evil!”

Dinah Craik (1826–1887) English novelist and poet

“The spirit of fellowship, with its attendant cheerfulness, is in the air.”

L. P. Jacks (1860–1955) British educator, philosopher, and Unitarian minister

"The Peacefulness of Being at War." in The New Republic (11 September 1915), p. 152.
Context: The spirit of fellowship, with its attendant cheerfulness, is in the air. It is comparatively easy to love one's neighbor when we realize that he and we are common servants and common sufferers in the same cause. A deep breath of that spirit has passed into the life of England. No doubt the same thing has happened elsewhere.
