人们常常以为:人在实践中碰的钉子多了,处理问题的聪明才智也就自然会成长起来。这就是所谓的“吃一堑长一智”。实际上,这句话并不是要告诉人们——凡是吃一堑必能长一智;而是要告诉人们——聪明人应该努力学习如何才能凡是吃一堑必定长一智。换句话也就是说:人应该学会如何有效地从失败的经验中总结出有益的教训,寻找出避免再遭遇同样失败的规律。 People often think: people in practice touched more nails, dealing with the problem of the wisdom will naturally grow up. This is the so-called “eating a long wisdom.” In fact, this sentence is not meant to tell people that everybody who has to eat a cut must be able to grow wise; but to tell people that wise men should try hard to learn how to be wise and long before they eat a cut. In other words: people should learn how to effectively sum up useful lessons from the experience of failure and find out the law to avoid the same failure again.
