臺灣籍旅美老師今天交給我們的句子是：

And if you're unsure whether something only concerns you, it's probably because you're committing the fourth mistake — not soliciting feedback. You don't want to go on for minutes on end lecturing. There should be opportunities for people to ask questions if they're truly engaged.
而如果你不確定什么事是只有你才會在乎（別人不太會有興趣），那么應該是因為你正犯下了第四個錯誤：不求取回應。你不會想要連續幾分鐘下來一直不停地說教。如果對方真的感興趣，他們應該要有機會可以發問。

學習重點：

1.unsure 缺乏信心的
unsure (adj.) 缺乏信心的
sure (adj.) 一定的

2.concern 關于、關心
concern (v.) 關于、關心
concerning (n.) 關于

3.commit 犯
commit (v.) 犯
commitment (n.) 托付

4.solicit 懇求、請求
solicit (v.) 懇求、請求
solicitation (n.) 懇請
