My physical flashcards system is starting to take shape, and I think I might actually stick to it for longer
I'm using a form of the Leitner system for the reviews in the morning, with just reviewing a bunch of cards from each section that is almost full, instead of some elaborate away of counting days or whatever.
Also, against everyone's better judgement, I'm mixing three languages (German, Spanish, and Arabic) to keep my brain on its toes 
(I could really use a blog to describe the whole process. Feel free to reply if you want to know more
)
