The word "paddling" is often used to describe someone who is not good at work or study and is just killing time. And "rowing class" refers to some boring, ineffective and meaningless courses or meetings in schools or companies. In other words, these courses or meetings are just a waste of time without any substantial gains.

In schools or companies, there are often some paddling classes or meetings. These boring activities will make us feel a waste of time, and may also make us lose our enthusiasm for study or work. If we always waste time in these boring activities, we will lose our self-discipline and time management ability, which will affect our development and progress.

In order to avoid wasting time in school or company, we can take some measures to correct our behavior. First of all, we should be self-disciplined, take part in boring activities as little as possible, and pay more attention to important matters in study or work. Secondly, you can find interesting activities to enrich your life and enhance your interest in learning and enthusiasm for work. Finally, we need to establish good time management habits, allocate time to different tasks reasonably, and improve our efficiency and ability. These methods can help us avoid wasting time in school or company and make ourselves more focused and active in study or work.
