Learn Japanese

Hey all, my goal is to be at an ability level where I would be comfortable living in Tokyo while working at a company that speaks English in the office.

To that end, I've been working through Genki and its workbook. I've noticed that the slowest part for me is the workbook exercises, because of all of the writing I'm doing. Additionally, while I'm learning kanji (through WaniKani) I'm not trying to learn how to write it. So I'm doing all of these exercises by writing down kana. This is starting to seem a little ridiculous because trying to read my kana-only answers is challenging (the kanji apparently helps me read).

Do I keep going like through all of Genki and even through Quartet? Or should I call it quits and start typing my answers?
