Man needs to choose, not just accept his destiny.
We can never judge the lives of others, because each person knows only their own pain and renunciation. It's one thing to feel that you are on the right path, but it's another to think that yours is the only path.
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.
