We want our children to succeed, in school and, perhaps even more importantly, in life. But the paradox(悖论) is that our children can only truly succeed if they first learn how to fail. Consider the finding that world-class figure skaters fall over more often in practice than low-level figure skaters. At first sight this seems contradictory. Why are the really good skaters falling over the most?

    The reason is actually quite simple. Top skaters are constantly challenging themselves in practice, attempting jumps that stretch their limitations. This is why they fall over so often, but it is precisely why they learn so fast. Lower-level skaters have a quite different approach. They are always attempting jumps they can already do very easily, remaining within their comfort zone. This is why they don't fall over. In a superficial sense, they look successful, because they are always on their feet. The truth, however, is that by never failing, they never progress.

    What is true of skating is also true of life. James Dyson worked through 5,126 failed prototypes(原型) for his dual cyclone vacuum before coining up with the design that made his fortune. These failures were essential to the pathway of learning. As Dyson put it: “You can't develop new technology unless you test new ideas and learn when things go wrong. Failure is essential to invention.”

    In healthcare, however, things are very different. Clinicians don't like to admit to failure, partly because they have healthy egos(自我)(particularly the senior doctors) and partly because they fear litigation(诉讼). The consequence is that instead of learning from failure, healthcare often covers up failure. The direct consequence is that the same mistakes are repeated. According to the Journal of Patient Safety, 400,000 people die every year in American hospitals alone due to preventable error. Until healthcare learns to respond positively to failure, things will not improve.

    But let us return to children. One of the major mistakes in education in the 1970s was the attempt to equip children with confidence by giving them lots of successes （setting the bar very low）. The consequence was that the ego of kids became bound up with success, and they became unable to take risks and collapsed as soon as they hit a proper challenge.

    We need to flip(翻转) this approach. In a complex world, failure is inevitable. It is those individuals and institutions that have the flexibility to face up to failure, learn the lessons and adapt which eventually excel(突出).

中国人民银行决定，自2014年11月22日起下调金融机构人民币贷款和存款基准利率。这是央行时隔两年多的首次降息，这次降息目的就在于发挥基准利率的引导作用，解决当前金融市场“融资贵、融资难”的问题，发挥虚拟经济对实体经济的助推作用。

虚拟经济，简言之，就是直接以钱生钱的活动，金融业是虚拟经济的核心产业。与虚拟经济概念相对的实体经济，则是指以提供现实的具有价值的产品或服务为基础的经济活动。现代经济发展离不开金融，金融创新推动虚拟经济的发展，为筹资、融资提供便利，促进了国际贸易和实体经济的发展；但脱离实体经济的金融发展，会加大经济发展风险。国际金融危机是实体经济和虚拟经济长期失衡的结果，给人们敲响了警钟，过分追求虚拟经济会带来巨大的风险，这启示我们要正确认识和处理实体经济与虚拟经济的关系。

结合上述材料，运用所学知识，谈谈如何认识虚拟经济和实体经济的对立统一关系。
