According to the passage,there are many students

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(无计划地进行),

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 theycan 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.Thereare many who shyThereare many who shy away from a self-controlled weekly timetable,and dislike being tieddown to a fixed program of work.Many able students state that they work in cycles.Whenthey 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 fullyunderstand the motivation to work.Most people over 25 years of age have become usedto a work routine,and the majority of really productive workers set aside regular hours forthe more important areas of their work.The "tough-minded" school of workers doesn't fullyaccept the idea that good work can only be done naturally,under the influence of inspiration.

Those who believe that they need only work and studyas the fit takes themhave a mistakenbelief either in their own talent or in the value of "freedom".Freedom from control and discipline(纪律)leads to unhappiness rather than to "self-expression" or "personality development".Oursociety insists on regular habits,timekeeping and punctuality,and whether we like it or not,if wemean to make our way in society,we have to meet its demands.
