I just read through some of John Fotheringham's Master Japanese ebook, of which the sixth edition was just released, and it's got some a lot of good advice in there, well-packaged. If you want some inspiration for your Japanese learning, it'll be worth a buy:

(Not that I'm learning Japanese, but I read the general language-learning parts, which is about 1/3 of it.)
