The narrow way is demanding but life-giving. 'Few find it' is not a discouragement but a call to seek it actively. Real life — eternal life — is worth the narrow path.
Memory phrase: The narrow way leads to life
Talk about it: If something is hard and few people find it, does that make it less worth having? Give an example.
Prayer: Jesus, You are the narrow gate. Help me follow You and not just the crowd.
