From last week’s article called “Time Runs like Usain Bolt”, the quote, “Money cannot buy time” piqued my interest and urged me to write this article for The Postech Times. I intend to expose alternative points of view on the topic. I believe money can buy time - no matter how bizarre this argument may sound. I agree that time is uncontrollable; you cannot stop time. However, with money, we can “buy” time by using money to remove inappropriate usage of time. One possible inappropriate usage of time is the process of waiting. Money can significantly reduce the amount of time we have to wait. For example, people who can afford Korea Train eXpress (KTX) have to spend less time waiting to get to their destinations compared to people who cannot afford transportation and have to walk. The idea of paying to reduce the time spent waiting includes transportation, communication, and many other aspects of life. In addition, as part of the engineering community, we Postechians, have already spent a vast amount of resources in reducing the time spent waiting in many cases. We are trying to optimize solutions to problems. Thus, we are the ones who are, technically, selling time. As merchants of time, we should believe people can buy time and we can sell time.
One may argue if people enjoy waiting, the idea of buying time might be invalid. However, I want to borrow a quote from John Lennon: “Time you enjoy wasting is not wasted time.” As human beings, we ultimately want to be happy, and enjoying an activity is part of being happy. If someone enjoys waiting, it is not wasted time; waiting is part of his or her happiness. Besides, people usually regret big mistakes rather than small ones. It is hard to imagine people regretting about wasting their fifteen minute break between classes. If I refine the suggestions of Reporter Lee Ji-a, I want to ask people to stop wasting time on activities they do not enjoy. I hope people use this piece of advice in the context of their own life, and make personal decisions, for everyone has different desires, problems, and beliefs - I hope nobody quits school. 
Moreover, I agree planning is important, but there are few hazards of planning. Planning may consume too much time. For example, I used to be a rigorous planner. Like Lee suggested, I made “concrete” plans for everything, and sometimes, time was spent more on planning than doing the activities I intended to. In the end, I had plans, but no output. The solution was to set a time by which planning had to be completed. There are also two ways planning can lead to depression. Assuming and predicting the future is part of planning, but, in reality, the future is unpredictable. Moreover, the further into the future you predict, the more uncertainties exist. The uncertainties may lead to insecurity and, eventually, to depression. On the other hand, people tend to get depressed if they are unable to fulfill their plans for the day. Just realize plans are tools for success rather than the measurement of competence. All in all, buy time if you can, enjoy wasting time, and have a balance between planning and making outputs.
