David O. Mckay said this quote

Man is a spiritual being, a soul, and at some period of his life everyone is possessed with an irresistible desire to know his relationship to the Infinite. . . . There is something within him which urges him to rise above himself, to control his environment, to master the body and all things physical and live in a higher and more beautiful world.

~ David O. Mckay

Well,’ you may ask, ‘how may I know when I am in love?’. . . George Q. Morris [who later became a member of the Quorum of the Twelve Apostles, gave this reply]: ‘My mother once said that if you meet a girl in whose presence you feel a desire to achieve, who inspires you to do your best, and to make the most of yourself, such a young woman is worthy of your love and is awakening love in your heart.

~ David O. Mckay

Happiness consists not of having, but of being; not of possessing, but of enjoying. It is a warm glow of the heart at peace with itself. A martyr at the stake may have happiness that a king on his throne might envy. Man is the creator of his own happiness. It is the aroma of life, lived in harmony with high ideals. For what a man has he may be dependent upon others; what he is rests with him alone.

~ David O. Mckay

The purpose of the gospel is to make bad men good and good men better, and to change human nature.
