May be 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, such as “Why should I suffer this? ” or “Isn’t there a 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 “trying to find a better way ” by smart workers. There was a large soap factory in Japan. Once it received an unusual letter from someone who complained that there was no soap in the soap in the soapbox he bought.How could empty soapboxes go out of the factory? The engineers checked the producing and packing. The producing was fine, but in about ten thousand soapboxes, the packing machine let an empty soapbox go. There was no need to spend a lot of money repairing the machine for such a small problem. The engineer soon worked out a solution. He put a huge X-ray machine and two large computers to find out the empty soapboxes. After teaching the workers how to use it, he sat down in his seat, exhausted.“Sir, we could have solved the problem in a much simpler and cheaper way, ” a worker sa id.“Really? How?”“We can put a huge fan near the packing machine. The wind coming from the fan will blow away the empty boxes, leaving the other boxes with soap. ”See, this is smart work. In order to succeed, we should not only work hard like the engineer, but also think smart like this worker.1.
