My essay
Over the course of my life, there have been a few influential figures. However, the one person who stands out above the rest as being pivotal in my development is my High School Mathematics teacher, Mr. Phan Huy Tinh. Not only has he had instilled in me a genuine thirst for knowledge, but he also inspired the course I wish to pursue in my future studies.

In my first experiences of working with Mr. Tinh, he fundamentally changed the way I learned and looked at Math. This teacher did not demand my classmates and me to practice numerous Math exercises; he frequently explained to us that solving a Math problem is not as important as finding out the way people generated it, and so he encouraged us to take the responsibility of creating new Math exercises ourselves. For me, such methods of learning Math were not only innovative, but also refreshing as we were able to become fully immersed in the study of Math. Studying in that way, I really learned to love the entire Math discipline. As a result, I achieved two 'Prizes of National Mathematics Olympiad'. For this, I am genuinely indebted and thankful for the efforts of my teacher.

He was also extremely beneficial in steering my decision for University courses. As mentioned above, I love Math and I had previously dreamed that I would become a mathematician. I was always certain that after I finished High School, I would apply to study at a Math School in University. However, I approached my teacher to ask his opinion and he advised me that, although being a mathematician is an interesting occupation and will offer exciting challenges, in the present state of affairs my country does not need more Math theorems. Instead, what Vietnam is now lacking is Technology: new technology for Industrial and Economic Development. The Vietnamese industry is really in crying out for talented engineers with an innovative perspective. I spent a lot of time pondering this, until finally I decided to follow my teacher's wisdom. I will become an engineer and be equipped to contribute more towards my country's development, as my teacher foretold.

I am applying for XYZ because I feel certain the XYZ is the best technology universities in the world and will offer me the best platform from which to succeed in achieving my goals. Furthermore, I am sure my teacher will be extremely proud if I study at XYZ in the next academic year.
