TUse "desirable difficulty"
运用“适当增加难度”来复习
Reviewing material is one of the most popular forms of learning. Guess what? It's also one of the least effective. Researchers call this "the fluency illusion." Just because it's easy to remember right now doesn't mean it will stay that way. "Desirable difficulty" means that the harder you work trying to retrieve something from memory, the better you learn. Don't merely reread stuff. Practice like a medical student and quiz yourself with flashcards. You're not going to learn much passively. Research show re-reading material four times was not nearly as effective as reading it once and writing a summary.
复习是学习的重要一环，那我要说是最没有效率的一环呢?研究学家称它为“熟练的假象”你记得某个知识并不代表着在任何情况下你都能熟练运用。“适当增加难度”的意义在于，你越难回忆起某个知识，你就会记得越牢。不要就简单的复读，可以学习医学院的学生利用闪卡来测试自己。不要被动的学习，研究表明，一本书你读四遍的效果不如你读一遍然后写一篇读书小结来的好。
You need to struggle. Whether it's memorizing information or practicing a sport or skill, you want your practice to be challenging. When I spoke to Dan Coyle, bestselling author of The Talent Code, he said: We learn when we're in our discomfort zone. When you're struggling, that's when you're getting smarter. The more time you spend there, the faster you learn. It's better to spend a very, very high quality ten minutes, or even 10 seconds, than it is to spend a mediocre hour.
你得受点挫折，不管是在记忆方面或是锻炼某项运动或其他技能。要尽量做些有挑战性的任务。就像《一万个小时天才》的作者Dan Colye所说，在我们舒适区以外，我们最能学到东西。就是俗话说的“吃一堑，长一智”，花越多的时间钻研，你就会学习得越快。聚精会神的十分钟，哪怕是10秒钟，比一个小时的磨洋工要有效率的多。
The Get fast, negative feedback
快速从失败中吸取经验
One of the three key components to "10,000 hours of deliberate practice" is feedback. Without it you don't know if you're improving or what you need to work on next. And don't just listen to me because I read the nerdy research. The most un-nerdy people in the world are on the same page. When I spoke to Navy SEAL platoon commander James Waters, he said feedback is critical.
关于“一万小时刻意训练”三个要素的其中之一就是反馈。如果没有反馈那么你就不知道自己哪里需要提高，下一步的训练计划要怎么制定。也不必只听我的一家之言，事实上，那些取得成绩的人都知道反馈的重要性。比如海军海豹突击队指挥官James Water 就认同反馈的重要性。
After every mission, SEALs do a review of what happened to get feedback. Do they all just congratulate each other? No, they spend 90 percent of their time on the negative: what they can do better next time. And there's another vital source of feedback: yourself. Always take some time to reflect on how you're doing.
每次任务结束之后，队员们就会对发生的事情进行意见收集反馈。难道他们仅仅是为了庆祝任务完成，当然不是，他们90%的时间都花在对于问题研究，下一次怎样才能做的更好。还有一项重要的反馈就是自我评价，每次对于自己的表现进行评价。
