I find the videos pretty engaging to be honest. They’re not hugely long either (under 20 mins 95% of them? 
). I think going for the 1 video/day approach is a good one. Not too much that it overwhelms you, but still with great results when you do it consistently for months.
You can buy a printed version of it on Amazon, or print it yourself. Here’s a PDF. The author has no problem with people getting it printed like that. He’s the one giving the pdf file for free (it’s on his website).
I’d say… do Genki. If there’s something you’d like to understand a little bit better, check the explanation of it on the Tae Kim’s grammar guide. There’s also Bunpro, a service you might be interesting in knowing about. They have the grammar points where you can use SRS like Wanikani has. I’m personally not a fan of SRSing grammar, but a huge fan on how they order grammar and the sources they share.
Yeah, I felt the same with Anki. Kitsun works much better for me because most decks also make sure you type your answers. I know the creator personally (he’s a WK user) and I know that it has a good promissing future. Then again, Kitsun will be pay to use in a few months, while Anki is free (iOS app is $25 or so).
