What if we had no courage to do anything, what would our lives be like?
Courage is not the absence of fear but rather the judgement that something else is more important than fear. The brave may not live forever, but the cautious do not live at all.

There are many quotes and inchanted speeches for motivation, life, love. But there is no such thing when it comes to the never ending fall. How can one save themselves if they fall in a black hole? Believing everything is fine is much easier than thinking about it. 

Sometimes when you're dancing on the edge of the world, you forget the risk of falling
