Life is another name of hurdle. Life is full of ups and downs. It teach us how to face this hurdle and come out as a warrior. We can not always win over it, we would face a loss and difficulties. But later we learn to accept the loss and move on from it. We won't sit at one place and cry for the thing that's not exist now at all in our life. Learn from that lesson and try to move on as soon as possible.
