I mean, to each their own, but when I was learning Japanese, I did just that: I immersed myself into the language with as many senses (?) as possible. Reading, writing, listening, imitating (called “shadowing”), literally talking to myself, plastering my walls with glossary and example sentences, forcing myself to read them out loud every time I would pass by one of the words or sentences hanging from my walls. Right until I realized that I had hit a barrier that could only be overcome by moving - at least temporarily - to Japan, which I did, but that’s another story.
