as a popular saying goes, time is money. in fact, time is more precious than money. when money is spent, you can earn it back if you want to. however, when time is gone, it will never come back. as the pace of modern life continues to accelerate ,the time at our disposal is quite limited. but there are a lot of things to be done in our lives. we should make full use of our time to fulfil what is useful to us. for instance, as students we should devote most of our time to our academic studies. in this way we can acquire new knowledge and skill necessary for our future carrier. in my opinion, wasting time means wasting our valuable life. but many of us dont realize this .they think time is inehaustable. im not in favor of such of a view .hence ,my conclusion is that we should never put off what can be today until tomorrow.
