Well, hard working in study is a very good attitude and behavior, and focus is the must for concentration and reading. But please don't forget to wear up your clothes or underwear before you study. See the girl at the picture, she is too focus and wear no underwear, but maybe we judge her too soon, maybe the weather is too hot that's why she don't want to wear it. All in all, she is very hard working! So, we should respect her strong concentration on study. ;)
