Good question.~
Good question. Actually, I don’t know how many words I can still remember after a day, a month or a year. But I bet I’ll learn more, much more than what I’ve done today if I can keep up with this kind of laborious working process day in and day out for a while. So I am not that worried.
BTW, should be “The problem is “ , not “the problems is” in your sentence. :)
