I started teaching myself a language recently. It wasn't my first choice, the teaching myself part... but there are no universities or colleges (or highschools, even) in Tofino... so all available courses would have been by correspondence or online, most of which are the "learn to speak whatever in however short a time! you'll be conversing with confidence and ease! woohoo!" type. I wasn't interested in speaking another language-- I speak enough of them-- I want to KNOW it. So I found a super reputable institution (known as _the_ authority on the language, sanctioned by the government, &c) and paid 525 euros for a correspondence course. After the first day, I had to (HAD to) refund it because it was TOTAL GARBAGE... worse than the "Teach Yourself" series available off the shelf at Chapters for $25.
SO as soon as I could, I went to the UBC bookstore (a six hour trip, each way) and bought the first year textbook package for the course that I could not take. I also picked up a couple of intermediate grammar books. Since I'm cocky and full of myself, I started with the intermediate grammar books instead of the introductory textbook package. I finished the first half of one book, and felt that I had made great progress with the language. I had learnt so much! Tense, aspect, mood, voice, conjugation, word order, separable verbs, inseparable verbs... all off it! Yay!
Then I realized that I knew nothing about nouns.
Ooops.
Well, such things are bound to happen when learning in a vacuum.
