I started learning Japanese 4 months ago, and tried to invest at least 1h a day decyphering kanjies, learning new words and some grammar.

So far it's going pretty well. I've got half of 常用 kanjies under my belt and ~1500 words of vocabulary that allow me to get a basic understanding of what's going on in easy mangas.

1000 more words and I plan on getting N3 cert.
