I've been reviewing kanji almost every day, wirh very few lapses, since September, and have only got through 400-odd of the basic 2000. Maybe 500 if you factor in disambiguations, where I have to track down all the kanji I regularly confuse this one with. (As eg 既 即 却 概 慨 or 疑 擬 凝) And review the ones I've covered, and review and review and review because I'll still be writing 殴 for 投, or vice versa, even after fifteen times through. I don't wonder why I'm doing it- it has no purpose but to fill the time- but I do wonder how long it will take to remember these kanji that I theoretically learned 30 years ago and more. Then again I note that after two years of strengthening exercises I can now do a bridge without my calves immediately cramping and spasming. So fine. How long will it take? Forever.
