Maybe you have seen this in schools:some students are studying nearly all the time but they just pass their exams,while some others may spend much less time on their books but do much better in exams.How could this happen?People used to think that hard work is the only way to success,but now they have understood that smart work can make them succeed,too.
Hard workers don't mind working for long hours,while smart workers always think of several different answers to these questions,"Why should I suffer this?”"Isn't there a better way to do this?”Thanks to these people,we can use computers instead of the abacus now. Progress in every field is the direct result of"try to find a better way”by smart workers
