I'm curious, how did things turn out a month later..did you ever start to get more motivated?
After reading through these posts there is one thing that wasnt mentioned much that I think may or may not be helpful.
If you can afford it, you might benefit from formal study in the form of Japanese classes such as those at a local university (or private tutoring if classes arent your thing). I've read AJATT and while I agree with a lot of what he says, and the core philosophy of the site, I never was quite on board with his strong dislike for classes. I've been taking Japanese for the past year and a half at college and while I do wish at times things went faster, overall it has been an enjoyable experience. The first semester in particular was key, introducing the basics in a way that really stuck with me, and giving me a solid foundation in basic grammar and pronunciation, something that I felt was invaluable, and that it seemed like you didn't do as much studying with. After the first semester I felt that there was a bit less value to it, but I still feel like it's worth my time. It also gives a bit more structure to my studies, something it seems like you didnt have. I have a bit of the same issue, I can't commit to AJATT full time, so structure really helps me. Class forces me to commit about an hour or so of active studying per day, no matter what. At this point, I can understand the gist of anime without subs (so I might not get what the long monologues are about, but the shorter conversations I can probably understand).
That being said, it does cost money, which is something you said you didnt want to spend much of. But still, at least a semester might benefit you.
One key thing about the classes, it needs to be fun. I took Latin in high school and it bored me to exhaustion (I actually had fun trying to wake up my neighbor who would never stay awake past 5 minutes, it was guaranteed that neither of us were paying attention). But my classes in college are fun, the students are engaged, and the teachers are energetic, want to help us, and are all native speakers. It's a joy at the end of the day to go to my Japanese class, and homework rarely feels like too much of a chore (not ideal, but it's better than Physics, and I can often feel things sinking in after the exercises. I believe that AJATT was against the type of boring and useless classes, but I don't think that he ever tried with more entertaining classes.
3 more things:
1) Get a good electronic dictionary, preferably one that can go on a mobile device like an ipod. I use the Midori app ($5-$10 in the itunes store) and it's been invaluable for quick look up and doesnt require me to switch to another tab and wait for the page to load, it's instantaneous and in my opinion decent for a dictionary.
2)
http://www3.nhk.or.jp/news/easy/ <== This is a site that I found on another post a few days ago, from what I can see it's like a kids version of NHK news and most of the kanji are with furigana. Combined with a good dictionary app and you can probably get the gist of the news article.
3) Subs, while a bit of a crutch later on, can be fairly useful in the beginning. There are a bunch of words that I learned the approximate meaning for because I kept hearing them and finally matched them to the sub I saw. It's not perfect, but can be a useful way to acquire vocab if you just don't get any of it. Plus, I tend to enjoy media more when I actually get what's going on
To me at this point, I know I don't have enough vocab to completely understand what's going on like I do with English (i'm also still going through RTK 1, so I'm putting a fair amount of energy into that at the moment). But I'm often satisfied with understanding the gist of what's going on the conversation, after all communication of ideas is a key bit of language. If I can understand that my Japanese speaking friends "A" and "B" had a great time in New York last week, then that gives me a little burst of joy as I know what they are talking about...that's more than I could probably say for myself a few months ago. I get even more excited when I can understand exactly what they are saying. I'm not yet satisfied with my language ability, but I'm more or less happy with where I am now. And I do think that a good language class might be worth your time if only to just give you a solid foundation to build on.
**One last thing, I promise. Take a look at this books:
Japanese the Manga Way- sort of textbookish, using manga to teach you. It's pretty good at teaching stuff that some of the more formal textbooks like Genki sort of gloss over, such as the type of informal language you might see more in Manga
A Dictionary of Basic Japanese Grammar (and intermediate and advanced when the time comes)- a pretty decent reference book that gets recommended a lot
and finally some sort of book devoted to particles, which could also be used as a reference book- I got All About Particles:A Handbook of Japanese Function Words , havent started looking through it yet, but something to explain all the particles might be helpful instead of trying to puzzle them out yourself
