Right, effort does NOT return void. However, the return is not equal for everyone, and the method used will effect gain. Forgive me for this long post, but I want to challenge your thinking on kanji-cards ( for learning readings at least ).
May I present a problem with learning Kanji+readings with most flash-cards? When reviewing, you will say, "yeah, I know that card," but I challenge you to try writing/typing the answer before you see it. It may be that you recognize the readings, but cannot actually bring them to memory on your own.
Of course, you will surely have memorized many using flash-cards, but ?inevitably? you may find your recognition becomes dulled as like-readings for many Kanji appear, or worse, your brain hasn't recognized the readings as important.
Solution? Now, this probably sounds silly, but I suggest using a quiz-ing software that allows you to type( writing would take waay too long, that's why we use anki after all ) in the readings and English. Of course, the software needs to give you more than simply a quiz, but also give you common Kanji compounds that uses the Kanji's readings (Or the ability for you to input your own).
Drawback? It is best to START using this method from the beginning. I presume it will be discouraging to use this method if you are forced to relearn your Kanji ( even if you have the advantage of already "knowing" the Kanji ).
Drawback#2: Only has JLPT2 and up, needs more Kanji cards.
Drawback#3: Needs used daily. 1-3 times (1-3hrs ) a day. Time away will allow memory to dull, there are lots of Kanji to remember.
Crazy?
