"Thoughts mold your features. Thoughts lift your soul heavenward or drag you toward hell. … As nothing reveals character like the company we like and keep, so nothing foretells futurity like the thoughts over which we brood. … To have the approval of your conscience when you are alone with your thoughts is like being in the company of true and loving friends. To merit your own self-respect gives strength to character. Conscience is the link that binds your soul to the spirit of God."
-President David O. McKay, "Developing Character", Ensign, Oct. 2001, 22
