Lorenzo Snow

“Where a person is always complaining and feeling to find fault, the Spirit of the Lord is not very abundant in his heart. If a person wants to enjoy the Spirit of the Lord, let him, when something of a very disagreeable nature comes along, think how worse the circumstances might be, or think of something worse that he has experienced in the past. Always cultivate a spirit of gratitude. It is actually the duty of every Latter-day Saint to cultivate a spirit of gratitude” (The Teachings of Lorenzo Snow, p. 61-62).
