While I was in 9 th grade, I built a circuit (电路装置) for the traffic system of our city. After getting the first prize. I got this valuable advice from my father; “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.” I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (编码). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I  kept working and discussed with my professor, I became more comfortable and those “how ”questions soon turned into “what if I do this and that” types of questions. It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He has headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem. My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project. 59．According to the passage, the writer was interested in .
