My succsess/failure

Well one of my favourite succsess is: 
When i had 9 years old and i was studing 4th grade in primary school, I won my first spelling bee. 
I loved that moment because I felt that I was the most intelligent boy in the school, all my teachers gave me their congratulations, my mom was very happy and the best of all was that I received a diploma.

The worst failure I had: 
When I had 10 years old in my second period of exams in 5th grade in primary school, I had failed for first time in all my life the exam of Social Science.
I don't like that day of my life because I thought all the day in the school that my mom was going to complain me for failing the exam; but when i arrived at home I did'nt want to tell my mom so I went with my brother and I told him what happened. 
He recomended me to go and talk with my mom about the fail, so I went and I talked with my mom, She told my that, that was the consequence for no studying the last night and that was all she said.
