Yes, it takes commitment to master a language. In the case of Japanese, which traditionally takes the most weeks to master when coming from English, we made Japanese Complete based on frequency analysis to help speed up the process of acquisition. With 777 kanji carefully selected by frequency you can get 90% coverage of kanji in the wild. This is about a third of the "daily use" set of ~2200 kanji so the process is greatly accelerated. If you're interested in seeing what 777 kanji look like, I recently created a small kanji quiz game that quizzes by English meaning words [0].
Very cool; and pretty too!
