I still well remember it was that I was in Senior Grade One. Every one of my class said I was smart and clever, but I fancied myself too. But to my great disappoint, I failed in a very important test. See through my puzzle, my head teacher said me, " Failure comes from lack of efforts rather than lack of ability. " It was his word that woke me up. From now on I spared no efforts to study and made a great progress in the end. I have realized that we failed because we don't try your best rather than we are not intelligent.
