距离上一次更新又过去了 45 - 27 = 18 周, 四个半月; 说长不长, 说短不短, 足够发生很多事情;

之前不知道犯了什么病了, 老是想用英语来写博客. 可能确实内心里还是有些 “冲国人不能纯玩” 的想法, 写点小东西都要考虑收获点什么.

TLDR;

I get diagnosed as ADHD, and get some drugs (Vyvanse). It works pretty well, and changed my life a lot.

I conducted a personal case study this weekend: I didn’t take my Vyvanse for two days, and the results were a noticeable increase in pacing around, getting easily distracted, and feeling irritable towards my family.

For friends who suspect they might have ADHD, and feel it has already affected life, study, work, and relationship, I highly recommend using self-assessment scales for self-testing:

Important Updates

• Update at Oct 11, 2025. With Claude Sonnet 4.5 and gpt-5-codex, I think I do not need beast mode anymore. Just give a hint, read doc from “https://” and follow the instruction, AI Coding Agent will handle the rest.

So what is Beast Mode?

It’s a typical prompt engineering / context engineering trick that allows you to get the most out of Claude Code or other code agents.

Long time no see!

It has been a while since last time I wrote something.

I did have some expressions to share. I logged them into my Notion, and the next time I review them days later, I think, fine, that thing is not that important, I can just let it go.
