If you're concerned about the window's position, ancient Feng Shui advised the window should be located to your side, specifically on the side of the hand you don't use for writing. I think their reasoning was: this way, your head and the hand you use for writing won't cast shadows on the area where you're writing.

The reason is that if you're truly good at something, if you have a real talent for it, then it's easy for you to do it well from the start, so you rarely judge it or realize how good you are. Just as no one thinks they're good at their heartbeat and breathing. Because you have the talent to be good at them from the beginning, so you don't put in much effort to learn them, and therefore you don't realize how difficult they are.

I think a real way to discover your strengths is not to reflect on what you do well, but on what makes you most frustrated when you see others doing it. It feels like an experienced driver watching a student drive and getting frustrated: Why can't you do such a simple action correctly? If you find yourself constantly wondering on something: why can't everyone just do this and it's so simple? You can remind yourself that that one might not be simple at all, but rather that you possess a genuine talent for it.

1. This chatbot is incredibly fast. It's the fastest chatbot I've ever seen. Before this, I was used to waiting several or tens of seconds after speaking before the response appeared word by word. But this one immediately displayed a complete answer, which was a completely new experience for me. Is it because of using local model?

2. I'm almost never influenced by any ads, but the ads it recommended really appealed to me. I even hoped they were real. I asked how to buy them and Googled similar products. This shocked me and led to a long self-reflection.

3. Another thing that shocked me is that someone can now create such a beautifully executed, product-level, non-profit thing, simply to showcase an ironic concept. (Even the experience is somehow better real products, see 1). This spectacular unrestrained use of productivity is epic. And this is precisely what AI brings. A double irony.

> I can guarantee that tones are not particularly useful and that you can communicate with native speakers with all the tones messed up, and that's perfectly fine.

Not at all. Tones are extremely important. If you have all the tones messed up, you can hardly communicate in Mandarin. It's true, as you said, that different regions of China have different dialects, and you'll find that people can communicate normally because: 1) The tonal differences in nearby regions are not too significant, and people can still try to understand based on context. And 2) In many cases, people switch to regular Mandarin when their dialects cannot communicate with each other. This is why Mandarin exists. It is an officially regulated dialect that all Chinese people learn, to solve the dialect problem among different regions. Chinese people may speak their own dialects at hometown, but when two Chinese people meet and find that their dialects cannot communicate, they immediately switch to Mandarin. Therefore, the tones in Mandarin are very important. To a considerable extent, Mandarin exists because of tones. You cannot communicate in it with messed up tones.
