Hi Nina, I liked your video but was somewhat surprised that you mentioned so little about learning vocabulary in context. I think it's been well established that, regardless of what you do, the vast majority of your vocabulary is acquired through "normal" activities, such as reading, listening, conversing and writing. Imo, doing the things you cover in your video would also be helpful to most people, but it probably is not where the bulk of your vocabulary is acquired, and it is certainly not a substitute for massive input and output. You probably already know that, and I wouldn't expect a whole video on it, but I was expecting a statement or two regarding it.
You also failed to mention what is, perhaps, the most cutting edge tool for learning vocabulary these days - reading tools. LingQ pioneered this, but there is an (arguably) better free software version called LWT, and cheaper pay versions OPLingo and Readlang. These are effective for all languages, but much more so for Chinese and Japanese.
Anyway, I liked the video overall. Keep up the good work!
