The AJATT is considered by many, so to speak the Bible of language learning (or language living, if you will). I too believe it so. However, as I was going to this method, I found on occasions, a few things that didn't fit me or were not that good. I know many of you will not agree on me with these. This is not a negative criticism on AJATT or a hate post. In fact, the method works very well. I just wanted to point out what I felt needs to be pointed out.
Here is reference to the AJATT method: http://plus.ajatt.com/nutshell/
Here are the things (in my opinion) the AJATT lacked and how I improved on it (to fit my needs).
1. Passive Audio Immersion
The AJATT states that you must, as much as possible, listen to audio that is completely in your L2. He states that even hearing it is just fine. So, having it played in the background through your speakers or earphones while you do something productive, even if it be in English, is counted as immersion. And I quote from his site, "Most of your time will be passive". Where the problem lies is not the "immersion" or the "audio immersion". The part where the problem lies is in the word "passive". Passive Immersion just doesn't work, and I'll tell you why. I have been watching anime (in its original language of course) ever since as child. Even up to know I am still watching anime. But all those time I haven't been able to understand a single word. Not even a simple おはよう or すみません(すまない). Why? Because I'm reading the subtitles, that's why. Our brain has that capacity to blur what's not important and concentrate on what is.
That's why if you try and solve a math problem while your friends talk in the background, you won't be able to understand what they're saying completely. Sure, you'll catch a few word from time to time, but 90% of the context is lost.
Now imagine, while you do your audio immersion, you do it actively. And how do you do that? You concentrate. You concentrate on what they are saying. Even if you don't understand. You try to make do with the words that you hear. And, you don't do anything at all while listening. If you must do something, you do something that's not mind challenging. You do something that doesn't require much thinking (doing laundry, doing the dishes, cooking, eating, exercising, etc.). The time it takes for you to improve is quicker. Thus I created a formula for effectiveness of immersion:
E=T*C
Where E is effectiveness of immersion, T is time, and C is concentration.
Sure, with AJATT your T (time) is bigger, but when it comes to C (concentration), not so. But if you do it so your concentration is bigger, even a little bit of time will equal when doing it for a long period of time, but not having a big concentration.
2. Visual Immersion (those you read: books, journals, sites)
AJATT does not put much emphasis with reading. I am not saying that it was not mentioned nor was it forgotten, but the emphasis isn't enough. I'd say this visual immersion is just as equally as important as audio immersion.
3. Output
I cannot emphasis enough on how important it is to speak. Speaking makes you more comfortable with a language, it makes you live the language. Since your goal is to become fluent, you need not hinder yourself by not speaking or by giving way too little attention to speaking. Speaking makes you closer to fluency, because you get to have fun with the language, you enjoy it, you use it. You don't speak because you understand, you understand because you speak.
4. AJATT - not for everyone
This is the part where AJATT doesn't talk about at all (please correct me if I'm wrong). AJATT does not mention that it is not simply for everyone (but as for me, it works well). The AJATT method may work for many or even most, but not all. The best way for one to learn a language, is rather hard. The way that one could learn is through using a method suitable for him. And there is only one person who could get that method from. And that person is him. He must device his own method by getting (or stealing) from other methods. Like me, and I'm sure several of you here, most of the method you use is not a 100% of a certain method you may have read or discovered online. Like mine, mine isn't 100%
AJATT, but I'd say around 80%. The core of this method, nevertheless, still relies on the two factors that makes AJATT: Immersion and SRS.
So there it is. I hope that, and I encourage that people discover their own techniques. I hope they do not make the mistake of missing the opportunity to self study. Even if these people believe that classes do work and it does work for them, I hope they do try to self study, and experiment with techniques. I believe that AJATT gives a good core, a good beginning, a good rule, in beginning or continuing on with a language.
Good Luck.

(joking)! And don’t let your friends or family make fun of you or browbeat you into going along to see the latest mindless flick with them. Don’t let them tell you that you “have to unplug sometimes”; they’re full of crap; they’re only saying that to get you to go along. Don’t let them tell you “you can do it later”. Will they be there for you when your Japanese sucks because you didn’t practice because you were always “going to do it later”? Do your friends know Japanese fluently? Probably not. Because if they did, they would understand why you need to do what you need to do, and they wouldn’t try to dissuade you from it. If they do know Japanese fluently, then they should know better than to attempt to strip you away from the very thing that got them fluent: constant practice.
