Remember when I was in elementary school, I, always, was a top #1 student in my class. Then, into junior
high & High school, gradually, I did not keep the glory of myself...
So, that is 小時了了
Lack of dedication, ambitious, and engaged in too many activities while I was in Junior & senior high school
Although I did not keep #1 score all the way, I do have a good memory on my study years
