As is vividly described by the drawing above, you will understand better “Too much work makes Jack a dull boy”. He has to attend so many training classes besides his school classes. There is no fun and freedom at all in his life. Consequently, holidays and weekends have become dull work-days. It is obvious that he is too tired to learn these lessons well with no interest.

In my opinion, spare-time training courses are a waste of time for many students. They might do better when they show interest in what they are learning. It is urgent that parents and teachers shouldn’t force these students to do what they are not willing to, and when learning is fun, surely they will do better than we expect!
