If it helps the people out there who want to learn Japanese on their own but don't know if it's possible, then I can help you.

From and earlier post of mine:

I started teaching myself from books when I was 16, graduated High School early so I could attend Purdue Calumet, passed Japanese 101, 102, 201 and 202 by testing out of the first three, took the 4th one in-class and became a student teacher for this fall. I'm going for the JLPT2 in December.

If it means anything, than it at least means it's possible. I started from learning from various book and websites, little by little changing the resources I use to better myself everyday. If I knew what I know now about studying Japanese when I first started, I could possibly be on a native level or at least in the proximity (This is also because I'm always talking with natives).

Here are the steps that I wish I had taken, but now use them everyday:

1. Learn Hiragana and Katakana. These are very important:

Teach Yourself Japanese (2.1 to 2.11 to hear pronunciation)

*2. Study Taekim from lesson one to the end, review from the beginning every Saturday (or whatever day of the week you're free, at least one day should be devoted to studying Taekim)

Use his forum if need be to ask questions (It's not the most active in the world, but expect an answer before the end of the day, or sometimes hour)

*3. Step 3, like step 2, is an ongoing process. Begin to think in Japanese, take what you know and constantly use it. Learn new Kanji every day, but learn them in words. Make Japanese a part of your life, constantly writing, speaking, reading, etc. If someone is in Japanese, try to read it. The more you read the more proficient you become.

4. Use this website to learn new words all the time. (I posted this on Taekim's forum):

There's (close to the middle) a quiz with 4480 of the most common or 必要な words. Obviously, that quiz would take forever, but the creator (and various other people), split it up into 344 smaller quizzes covering all of the main quiz in increments of 12 words.

Here's what I do: Take two of the quizzes and study them (24 words in all). Take these words and make them the focus of your studies for a week, constantly writing them and such. The next week, take 3 quizzes (36 words in all), and keep up this process.

5. When your Japanese as gotten to a good fluency, use this website to talk to Native Japanese speakers that are trying to learn English as well, and are happy to reciprocate your requests.

6. Watch things that have Japanese in them, mimic them the best you can (I am a musician, so I was able to catch on to the subtle flow in pitch). Listen to Japanese radio as well -- anything to hear how it all sounds.

*7*. The final step is to go out and try to find native Japanese to talk to. Do whatever you can to achieve this step, as it is very important. You need that immersion, I assure you.

I hope this helped.
