    While I was in 9th grade, I built a circuit 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. 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 o

f 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.
