You can't ever become fluent by learning sentences. I have read millions of English sentences and yet I am not fluent. AJATT means more than just learning sentences. It's about immersing yourself in the language. Also the number of sentences learned has no connection to your proficiency level. Someone might learn 10,000 simple sentences only to reach the same level that someone else can achieve by learning 1,000 complex sentences and doing other studies alongside. Furthermore it's important what and how much you study beside learning sentences, like reading books, watching Japanese TV etc.

You can say whatever you want to say, but if you two guys aren't fluent in English then I'm a monkey. And for the record, I consider myself not to be, act or look like a monkey . Apart from that, I think Sequa phrased it all well.
