True happiness comes from following Christ’s example and developing Christlike attributes such as obedience, goodness, honesty, gratitude, humility, love, charity, and forgiveness. It comes from serving others and helping them to follow Jesus Christ. It comes from controlling the appetites of our human bodies and following the promptings of the Spirit. It comes from working hard and having a healthy lifestyle, friends, family, and personal achievements.
