Oh a yearly reading challenge thread! That’s perfect for what I want to accomplish! 
My goal is to reach level 20 by April and level 30 by the end of the year. I recently revisited the anime 獣の奏者エリン while I was pregnant with my daughter last year. I’d like to make it my goal to be able to read the original novel by the beginning of next year, since it’s rated around 31 according to Natively. I’d also like to try to tackle キノの旅 which seems slightly easier to read at level 29, so I might try that first at the end of the year.
Until then, I’ll be sticking to the １０分で読める and なぜ？どうして？series for ES students this year. I don’t know if I can keep up with my reading when I have to go back to work in April while still raising our baby girl, but I’m gonna try!
