【TED】怎么利用20小时学习任何东西？ (Josh Kaufman | 20 Hours to Learn Anything (Key Points Talk))
Now, most skills have what I call a frustration barrier. By committing to practicing whatever it is you want to do for at least 20 hours, you will be able to overcome that initial frustration barrier and stick with the practice long enough to actually reap the rewards.
注意，大部份的技能学习时都会出现所谓的挫折障碍。无论想学什么，自我许诺至少练习20个小时你将能克服一开始的的挫折障碍，而能继续练习，坚持到时间长度确实足以获得回馈。

These labels don’t require a researcher: Teachers can automatically and involuntarily apply them to students. So, it is especially important to grapple with and examine the expectations attached to them.
这些标签不需要研究员：老师会自动地丶不由自主地将学生贴上标签。所以，尽力了解和审查附加在标签上的期望显得尤其重要
