A subtle and important detail: folly targets people already on the right road. Temptation often comes to those already trying to do right, not just those wandering aimlessly.
Memory phrase: Folly tries to pull you off the right path.
Talk about it: Have you ever been doing the right thing and then been tempted to go a different way? What happened?
Prayer: God, when I am on the right path, help me keep going. Do not let me be pulled away by things that look exciting but lead nowhere good.
