Have you tried using Wanikani? I have been using it for less than half a year and I already know more than 600 Kanji, most of which I can recognise in written text also. Of course, it helps if you reinforce the material through some other means, too, e.g. by working through a textbook.

disclaimer: not affiliated, and WK is not a perfect product (they have some weird quirks), but I've found it to be rather effective. You can also the first three levels for free.
