in my opinion，the mot important thing in the world i time.however long one may live，hi life conit of a certain number of year，and a year ha only12month，a month30day and one day24hour.once you wate one hour，you can not get it back no matter how much you would pay for it.
even though you are the richet peron in the world，you can not afford to wate your time，becaue it mean that you are wating your life.even though you are the mot powerful peron in the world，one hour ha60minute for you jut a for everyone ele who truggle at the bottom of the ociety.
ome people think that the mot important thing in the world i money.in their opinion，if you have enough money，you will have everything you want.i would like to ak them a imple quetion：can you buy time？
the only thing with which we can win more time i efficiency.if you work with high efficiency，you can do more in a certain period of time than other people.
