By and large I also started reading native material this year. That’s such a crazy thing to think about, I didn’t even really realize until you asked about the wrap up, @Naphthalene - thank you!
(I say by and large bc theoretically I started a manga on the 18th of Dec last year, but I didn’t really believe in myself and it was more stop than go until after February this year
)
What helped
Then from Feb 8th to 22nd I read the first volume of にゃんにゃん探偵団 because there was a thread and help for it, which removed a lot of the built up fear of failure
. Even so I had some trouble getting started. The fact that @NicoleRauch was also reading this book at the same time helped so much with getting and staying motivated. I’m truly grateful. 
I read like half of 時をかける which was a drag, and then jumped ships and joined the book club for キノ. Reading with others really did wonders for my motivation and growth into more difficult books.
After キノ finishing 時 went faster too.
Anyway, since this is turning more into an ode to the bookclubs than anything else, I’ll stop here. (Oh, and this thread obviously was a tremendous help as well, but I said that somewhere in this thread already. Probably more than once.
)
About goals
I passed my original goal of 5 books and 10 manga with 10 books and 33 manga read so far and may yet finish Re:ゼロ and キッチン.
I think next year I’ll try to aim for 12 books as well. One a month seems like a nice even reasonable amount. 
Favorites
That’s a bit more difficult. xD Everything considered, I probably liked コンビニ人間 most? It was a very good fit for my level, quite straightforward and all in all a very comfortable read. I also liked the protagonist and the way she saw and told the world.
Close seconds would be Re:ゼロ and キッチン. I enjoy the whimsical style of キッチン, but it sure is harder to read than コンビニ, even if the words and grammar used don’t feel more difficult. And Re:ゼロ is unexpectedly good, but having to look up so many words makes it a tad less enjoyable to me. 
As for manga, I’m enjoying よつばと! a lot more than I expected, but my fav this year was definitely 少女終末旅行. While the 1st volume wouldn’t necessarily have inspired me to keep reading, I’d kinda already bought the rest. And then I liked each consecutive volume more than the previous, so I’m very, very glad about it too. 
おわり
Right, that’s it. It’'s long enough. xD Sorry for rambling!
