Often it's the deepest pain which empowers you to grow into your  highest self.  I love this quote I believe that it has a ton of validity to it.  As any trial or tribulation that you experience in your life, it non the less grows you.  You might not see it at first but years later when you look back you can say, this tragedy grew me in this area.  Or taught me this, or even changed a part of me.  Hopefully in the best way.
