The best advice I received in my childhood was from my dad. He always gives me some advice, but I seldom took them seriously. One day he was encouraged me to participate in a speech competition. So I signed up and after the competition, I did my best to be full prepared. But the moment I stood on the stage, I was such nervous that my mind completely went blank. The experience of lose a competition was really painful. Then, my dad said, “My son, life is like battlefield. You have to lose many time to win the final victory.” Thanks for his advice, I never give up when I do anything.
