My father is an engineer. He works very hard.
Once 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=Y+Y+Z.
“What does it mean?”I asked.
“A means success，”explained my father. “X means hard, Y means good ways. and Z means you must stop talking and start to work.”
That’s right. From then on. I tried my best to be better.
