Youth is Money?

今天回總公司領書 二十本產險試題
I had no idea how heavy they are until this morning. I put them in a box, and carried the box to walk 150 meters to the nearest bus station. Then I know lifting is such a great exercise, for I felt warm immediately. Its weight is more than 10 kilos fore sure. Next time I will not going to do this again unless I have a company or get stronger.

Still, I am proud of it. Simply because I have no idea how heavy the books are at first, I am able to take action and complete the task.

Since youth is money, I'd better to use it well next time.
