34. 如何从错误中成长

2018

作为技术人员，是不是应该尽可能的多去试错，特别是伸展错误（stretch mistakes），进而从中学到东西。

Stretch mistakes happen when we’re working to expand our current abilities. … If we never made stretch mistakes, it would mean that we never truly challenged ourselves to learn new knowledge or skills.

无知错误（aha-moment mistakes）应该尽可能早的遇到，遇到不明白的地方尽早发问，即使被别人嘲讽，也不要藏着掖着，早遭遇早解决，避免再次犯同类错误。

Aha-moment mistakes happens when we achieve what we intend to do, but then realize it was a mistake to do so because of some knowledge we lacked which is now becoming apparent. … We can gain more aha moments from mistakes by being reflective.

粗心错误（sloppy mistakes）应该尽可能避免，而且不要一错再错。

Sloppy mistakes happen when we’re doing something we already know how to do, but we do it incorrectly because we lose concentration. We all make sloppy mistakes occasionally because we’re human.

高风险错误（high-stakes mistakes）可能是无法避免，也不收自己的控制，那么就只能在遇到之后，想办法减少损失，复盘总结经验。

… to seek to minimize mistakes and maximize performance in these events. We’re putting our best foot forward, trying to perform as best as we can. … we can always learn from these performance events by afterwards reflecting and discussing how things went, what we could do differently next time, and how we could adjust our practice.

年龄越大，遇到伸展错误的机会越少，而且即使是获得了试错学习的机会，成本也可能难以承受。做好复盘，尽可能提高犯错带来的收益。

无知错误其实越早遇到越好，和伸展错误一样，后面的试错成本可能比较高。有时候会觉得无知错误比较丢人，“连这么基础的东西都不知道”，但是如果假装自己知道，有可能会“被雷劈”，损失更大。

粗心错误需要尽可能的避免，特别是杜绝第二次发生类似的情况。

我觉得自己已经无法承担高风险的错误，年龄越大越保守。

上一篇提到的，“错误表扬对手”的错误应该属于无知错误，当时我以为已经拿到项目了，实际情况是拿到的可能性为 90%，但还没有最终确定。

丢失数据，属于粗心错误，多做一次验证就可以避免。

好像没怎么经历过伸展错误。突然意识到，自己踢球踢的不好，很可能就是因为自己没有试着提高技术水平、多做一个新的动作，所以……

其实大家都不甘心于做 CRUD 程序员

这篇文章最有价值的，其实就是这四种错误的分类，感觉有点类似程序的错误处理机制。

It is well to cultivate a friendly feeling towards error, to treat it as a companion inseparable from our lives, as something having a purpose which it truly has. - Maria Montessori
