LEARNING JAPANESE
There is an overabundance of information on how to learn Japanese. After spending too much time consuming it all, a combination of immersion + Spaced Repetition Software (SRS) works the best for me:
- > The most important benefit here is a measurable goal. Reaching a vocabulary of 10,000 words means conversational fluency (you'd know 99% of most common words)
- > To remember 10,000 words use SRS software like Anki
- > To find 10,0000 most common words for your use case immerse and "mine" those words into your SRS deck using Yomitan
- > Immersion means consuming content in native language (books, series, movies). Immersion is crucial for language acquisition (actually learning the language) instead of rote memorization. You can technically learn a language just by immersing, but an SRS speeds up the process and gives you a measurable goal (not to be underestimated).
- > To learn fundamental grammar use these weird Cure Dolly Lessons (YouTube, though I prefer the transcript)
