There is no doubt whether attending college can not only enlarge our knowledge but also improved our ability. Colleges are considered as the most beautiful places in the world, where we are likely to take the possession of the most wonderful time in our life. However, it's a pity that some students waste the precious time in college. It is not until they look for jobs that they regret not working harder. I hope we will value every minute. Only in this way will we not regret it when look back at the past.
