I know most of the joyou kanji and some others. Probably over 2000 but I stopped counting long ago. Yeah, fluent but not perfect. There's always a lot more to learn and I know I'll never know everything.

Your goal is totally attainable if you just keep at it. I started studying pretty late (25 or so) but I was still able to do it.

Excellent advice, thank you very much Senpai!
