When I turned 9 years old, I started to play soccer in a team. And my athletic ability dramatically improved a lot afterwards. I had been chosen as a relay racer at a school sports event every year until I enrolled in a high school. So I used to have strong confidence during the period. Actually cocky and over-confidence is the right way to say it.

But when I enrolled in the high school, my confidence took a hit because the high school I went to was known for a competitive soccer club and there were many athletic students and talented soccer players. I was a big reality check in my life.
