These days my work is mostly on the Internet. However, there is one ______ that I use nearly every day. And I learned it from my dad almost 40 years ago in a very different ______.

My father ran a plumbing(水管) shop. I had to ______ him with his work. One day, I was asked to work ______ a concrete floor. It wasn’t the kind of work I ______. The work was physical work which involved ______ a chisel(凿子) and swinging a five- pound hammer at it really ______. Often, my aim was bad ______ the hammer missed the chisel and ______ my wrist. After ten minutes, my dad came, expecting to find the job completed. Actually, it wasn’t. He asked, “Son, have you been doing it all the time?”“Well dad,” I told him ______, “I figure out a good way to do this more ______. I just tap the chisel and move it. I’m generating a circle of shock wave down into the concrete. That way, it’ll break along the lines and I won’t hurt my wrist again.” Dad gave me a ______ look. He said, “Son, just hit the thing.” Then Dad ______ me his hand. I saw many scars on it .He told me, “If you stick to the work, you’ll ______ it sooner. “ Well, I did hit it then. And the job only took five more minutes to finish. ______ enough, even though I hammered my ______ two or three times, I was proud that I’d just done it.

Today, nearly 40 years later, when I ______ any difficulty in work I still hear my father’s voice, “Son just hit the thing.”I feel ______ because I know he’s still urging me to take action, go ahead, get the job done, and never ______ the scars.  And that’s not a bad ______ to carry through life.
