If you ask me what is the most precious, I would say that it’s time. Time is something once lost, you could never h**e 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.
