Courage

"That you don't believe-- that's probably only because you don't believe in yourself. Because you've never ever committed yourself, made any decision on your own, and that's because you're too weak, too incapable, just like a caged bird that could never gather up enough courage to break through its cage and fly away." She let on a smile and continued, "Even if someone were to open that cage for you, you still wouldn't fly out, because you're afraid that the wind and rain will soak those beautiful feathers of yours."
