So for 2-3 years I have been using flash cards to get to 1000 kanji and then switch for full immersion and extrapolate meaning with some dictionary. I only know around 150 kanji.

This method already worked for english and russian but without flash cards part. I learned first 1000 words + grammar in school by osmosis thorough textbooks.

My routine is 30 min a day for two weeks and then 2 week break due to boredom or some other factor. It makes my backlog huge and discouraging and my retention seems terrible (60-70%)

For the past 6 month I didn't make any new flashcards to remember. only reviews of old ones.

Do y'all have some better method to get to 1000 kanji inefficiently? Because it seems efficient method doesn't work for me.
