Until two days ago what had driven him was the will to survive: deep, animal, full of rage but always part of him had not cared at all whether he lived or died. Now he did care, and very deeply, and so for the first time in a long time he was afraid. To love life is, of course, a wonderful thing, but not on this day of all days.
Life is filled with unanswered questions, but it is the courage to seek those answers that continues to give meaning to life. You can spend your life wallowing in despair, wondering why you were the one who was led towards the road strewn with pain, or you can be grateful that you are strong enough to survive it.
