Never give up

One of my friends won in a competition which organized in Sunday. I am very happy although I am the looser because I am satisfied to see amc win. But, of coarse it is better to be the winner. So, I try to find out what I did wrongly. And finally, I found the answer.

I am not sure my answer is correct, but I will try. I will not give up if I am wrong because it lead me to the road of success.
