“If there is one lament I cannot abide—and I hear it from adults as well as students—it is the poor, pitiful, withered cry, “Well, that’s just the way I am.” If you want to talk about discouragement, that phrase is one that discourages me. Though not a swearing man, I am always sorely tempted to try my hand when I hear that. Please spare me your speeches about “That’s just the way I am.” I’ve heard that from too many people who wanted to sin and call it psychology. And I use the word sin again to cover a vast range of habits, some seemingly innocent enough, that nevertheless bring discouragement and doubt and despair.
"You can change anything you want to change, and you can do it very fast. That’s another satanic suckerpunch—that it takes years and years and eons of eternity to repent. It takes exactly as long to repent as it takes you to say, “I’ll change”—and mean it. Of course there will be problems to work out and restitutions to make. You may well spend—indeed you had better spend—the rest of your life proving your repentance by its permanence. But change, growth, renewal, and repentance can come for you as instantaneously as for Alma and the sons of Mosiah.”
