With the advent of the era of knowledge economy, time is treasured by an increasing number of people. However, many young people attach little importance to punctuality, which, in my opinion, will give rise to many problems. First, you may impress other people as being unreliable and dishonest. When you are late for a job interview, the boss may refuse to give you the chance since people tend to assume that if you cannot fulfill your promise, you have no sense of responsibility and can do nothing well. Second, others may think that you show no respect to them. Therefore, university students should learn that punctuality is a good habit. Being punctual, you are showing respect to others and, in return, you will win others' respect and trust.
