There is nothing impossible to him who will try.
Once a King of Scottland Robert Bruce ruled over Scottland. He defeated many times by English solidiers. He ran for his life and hid himself in a cabe. He saw a sprider trying to reach its coweb. He failed 9th times after he he succeeded. He learnt a lesson and took his army to the battlefield and succeeded. Therefore it is rightly said try againn and again till you succeed.
