My main goal is to be as fluent in Japanese as possible.  To do that, I plan on passing one (or more) JLPT exams and learning the 1,945 常用漢字.  My progress is as follows:

JLPT 4 (103 Total) - Done

JLPT 3 (181 Total) - Done

JLPT 2 (739 Total) - 736 Left

JLPT 1 (903 Total) - Not Started

For learning 漢字, I use White Rabbit Press' flash cards and Anki.  They're invaluable resources for anyone who's serious about learning not only JLPT 漢字, but also for learning the most common compounds found in 日本語.  For a list of JLPT 4 to JLPT 2 漢字, please visit Peter van der Woude's JLPT Study Page.
