    By far the most common difficulty in study is simple failure to get down to regular concentrated work. This difficulty is much greater for those who do not work to a plan and have no regular routine of study. Many students muddle along, doing a bit of this subject or that, as the mood takes them, or letting their set work pile up until the last possible moment.

Few students work to a set timetable. They say that if they did work out a timetable for themselves they would not keep to it, or would have to change it frequently, since they can never predict (foresee) from one day to the next what their activities will be.

No doubt some students take much more kindly to a regular routine than others. There are many who shy away from a self-controlled weekly timetable, and dislike being tied down to a fixed programme of work . Many able students state that they work in cycles. When they become interested in a topic they work on it attentively for three or four days at a time. On other days they avoid work completely. It has to be admitted that we do not fully understand the motivation to work. Most people over 25 years of age have become used to a work routine, and the majority of really productive workers set aside regular hours for the more important areas of their work. The “tough-minded” school of workers doesn’t fully accept the idea that good work can only be done naturally, under the influence of inspiration.

Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of “freedom”. Freedom from control and discipline  leads to unhappiness rather than to “self-expression” or “personality development”. Our society insists on regular habits, timekeeping and punctuality (准时), and whether we like it or not, if we mean to make our way in society, we have to meet its demands.
