I can't do it. How does anyone learn this fucking language? My reps keep piling up day after day because I can't remember any cards. I end every review session in tears. Tonight I had to just mash "good" for me last 20 cards because I could not remember them after having seen them several times in this same session. I'm not going to remember them tomorrow, just like I haven't been able to remember them for weeks. I don't understand, I did everything the guide said, how did it end up like this? Why can't I learn this? Why am I so dumb?
