I wrote a book in 2014 and put it on my website for free download. The title is “Learn Any Language. The New Model”, it is in Russian, and it describes my experience of self-teaching a foreign language without the language environment and without a teacher. However, the book is meant not only for those lucky 7 % (according to some sources) of people who can achieve good results on their own, but for a wider audience as well, because it gives a detailed learning plan and provides a system, which is important in any process of skill acquisition.
That was also a good experience of mini-project management for me, as prior to the release I had to coordinate my work with the work of a designer, a programmer and a proofreader.
