日本語のworkbook

Zeroth step: know your tools:

Yomichan
A must-have for reading in Japanese: it lets you translate unknown words on-the-fly.
Simple Translate
Sometimes you just need a particular chunk of text translated. Use this, as opening Google Translate each time you need it gets really boring really fast.
Anki
The learning system. A truly powerful beast in the right hands, although getting quality decks is your job.
jpdb
My choice for Anki-style learning. It is very easy to use and the decks are quite good.

Don't waste your time with rōmaji: it will slow you down. Hiragana will let you read furigana above kanji, and understand the logic behind some key grammar points. Katakana is used to write most loan words, so it's useful too. Using them will also turn into a positive feedback loop — as you will be forced to read kana, you'll learn to read it faster.

Also, don't be scared of kanji. It will slow you to a crawl for a long time, that's normal. I will present some of them when required to understand the surrounding notes, not to make you learn them by heart.

You may wonder: how do I learn which verb belongs to which category? You don't. Just read a lot, use them, make mistakes and learn as you go.
