My father is an engineer. He does well in his work and earns people’s I asked my father what the secret of success was. He didn’t say a word, but wrote a few words on a piece of paper and handed it to me. I looked at the paper. On it was written: A=X+Y+Z.“What does it mean?”“A mean success,” explained my father. “X means hard work, Y means good ways, and Z means to stop talking and start to work.”“I see.”From that day I tried my best to be better. A=X+Y+Z. My father’s right.望采纳
