Which is more important, Quantity or Efficiency? Some time, the standard to judge success and failure is hard to decide. For some results, the quantity is most important, such as economy figures, which are easy to measure while efficiency is not used often to judge the results. To take our country- China as an example, we have achieved to be the second largest economy in the world. To some extent, we are so successful, but we have paid heavy price for those. Damage to the environment and consumption for nonrenewable natural resource are the main problems we faced while the rapid development of our economy. So for long extent, we are not so successful. Even we are overdrafting our future and the rapid development speed can last long. Another example, in relationships between lovers, boys maybe too busy to taking care of girls, but even when they spent many time (they think) on girls, girls are still not happy. Girls are also explaining that the boys can get the point to delight them no matter they stay with them all day. In other words, boys’ efficiency is too low to success. According to the above two examples, we find that to achieve a long-term goal we often pay more attention on efficiency, because short period benefit maybe destroy the whole plan.
