When you find your path, you must not be afraid. You need to have sufficient courage to make mistakes. Disappointment, defeat, and despair are the tools God uses to show us the way.
When I despair, I remember that all through history the way of truth and love have always won. There have been tyrants and murderers, and for a time, they can seem invincible, but in the end, they always fall. Think of it, always.
