you ask me what is the most precious, I would say that it’s time. Time is
something once lost, you could never have again. Therefore, we should cherish
it and spend it in meaningful things. However, many people do too many meaningless
things to kill their time, such as playing computer, watching TV, or gossiping.
When you do these things, the time has long been unwittingly flowed away. In my
opinion, the best way to make full use of time is planning your time rationally
and sticking the plan firmly. Spending more time on something significant not
only will make your life fulfilling, but also will give you a sense of
accomplishment. Instead, killing your time with meaningless things would bring
you depression even despair. Remember that those who abandon time will be also
abandoned by time.
