I’ve been engaging in rather intensive Japanese immersion for over a year now (we’re talking about an average of 4 hours a day alongside subliminal usage and day to day life).
I still get notable results from subliminal usage, sensing in-depth internal change and the occasional unexpected external manifestations pop up. I’m listening to Crown & Capital, R.I.C.H. Trader, and RAIKOV at the moment, and I’ve made serious headway in clearing much of the psychological and emotional baggage I accumulated over the years dealing with large sums of capital in the markets.
For example, the trades I took yesterday were executed beautifully, I’ve been getting serious about structuring my inner circle to distance myself from emotional/time leeches, and my confidence has been rebuilt as I continue to listen to the stack.
On the language acquisition front, I am where I expected to be on my ability to parse and understand the language, and it continues to improve on pace with what is expected given the amount of hours I’ve put in.
For a metric, my listening comprehension (which is the domain I focused on near exclusively for that first year) is around the JLPT N3-N2 level, and I engage in native content with surprisingly high comprehension at times, especially compared to where I started.
All of that said, this is a larger energy expenditure than just subliminals alone. Proper sleep is crucial, as is fueling appropriately and taking adequate breaks during the days that I immerse with difficult content.
The brain will require more glucose or ketones, and learning a new language will also build new neural connections - likely more than subliminal usage. (Japanese has multiple scripts, new phonetic mapping, tens of thousands of new words unrelated to English etymologies, etc.).
Exercise will help with any fatigue that could pop up. You and your body will calibrate to balance language learning and other subconscious work. Our minds and bodies are immensely powerful once in a routine.
One last thing: Learning a language is likely improving your brain function, which theoretically could enhance subliminal processing. Staying disciplined is easier for me now than a year ago, and I effectively feel like a new person (I’m in my late twenties, for reference).
Best wishes, and ease yourself into it! You’ll be glad you made the effort.
