Sometimes events that lead us bereft of anything but grief just happen for no reason other than happenstance--a car turns left instead of right, a train is missed, a call comes too late--and the real test of our humanness is whether, in light of that knowledge, we are ever able to recover. When we again find our way despite the inability to manufacture a deeper meaning in our suffering, that I think is when God smiles upon us, proud of the strength of his creation.
You have got to want to be the best before you can even begin to reach for that goal, and you have got to be prepared to sacrifice a lot to get there.
