Please answer the following question: Read the following article and select the best answer. Article: I am not just a successful architect . I also like to play the piano. In my spare time I often turn some dry musical symbols into beautiful music. Many years ago, while I was in a university studying architecture, I worked in a workshop. During the break I found an old piano in the corner of the room. With the allowance of the boss I sat down to have a try. Following my fingers the keys danced brilliantly and at the same time beautiful music flew out and then to every part of the room. All my workmates suddenly stopped talking and made their ears ready for my music. After graduation, I began to devote myself to my profession. All my musical talent was wasted into zero. Then one evening we went to a concert at which Mr. Stevenson, one of the ordinary workers in my company, sang us some beautiful songs. His musical talents made us all surprised. We all enjoyed ourselves with his beautiful voice so much that we even thought him a professional singer. I was also reminded of my musical talent. I began to train in a training center. My teacher was strict with me. He encouraged me to train every weekend and each time he asked me to play better than the last. Now I can proudly say I am also a successful pianist because every time I played on the stage fresh flowers and warm clapping would come from my audience. So I say, my friends, don't busy yourself with your work too much. Find some time to develop your potential talent and your life will become more wonderful.
