When I was young, I thought old people had everything figured out. Now that I'm old, I know this isn't true.

小时候，我以为老年人对一切都了然于胸。如今我年纪大了，才明白事实并非如此。

I constantly feel like a noob. It seems like I'm always talking to some startup working in a new field I know nothing about, or reading a book about a topic I don't understand well enough, or visiting some new country where I don't know how things work.

我总感觉自己像个新手。总是在和某个在新领域工作的初创公司交流，而我对这个领域一无所知；或者在读一本关于我不太了解的主题的书；又或者去一个我不熟悉当地情况的新国家。
