Here’s a few of my favorites:
“Never let a problem to be solved become more important than a person to be loved.” President Thomas S. Monson, Ensign, August 2011, 4.
“We are not called by God to do extraordinary things, but to do ordinary things with extraordinary love.” Jean Vanier, often repeated by Mother Teresa of Calcutta.
“Little children do have words given unto them many times, which confound the wise and the learned.” Alma 32:23
And of course the Primary theme: “All thy children shall be taught of the Lord; and great shall be the peace of thy children.” 3 Nephi 22:13
