Learning needs effort, and that's pretty clear, but not many folks truly understand this. Particularly when it comes to reading, some individuals only focus on the quantity of books they consume rather than the insights they can gain from them. Personally, I prefer using my Kindle to read, where I highlight noteworthy points and then transcribe those highlights into Notion. I'm not sure if writting down the highlights is better than speaking them out, but I find it to be quite effective.
The concept of a "learning box" sounds interesting, and it would be great if there were an extension for it.
