What I like best about these different study logs is seeing the different methods and resource used to study different things. =D
Depending on your schedule/availability to spend time on it, these could be the perfect opportunity to push yourself into getting your Japanese where it needs to be. This won’t work for everyone, but looking up everything you don’t understand can result in learning a lot. (Although it also risks leading to a quick burnout, so it depends on the reader’s learning style.)
Regarding Yotsuba, if you only tried volume one, I can definitely relate. I failed to make any progress with volume one back when I first tried reading it. After upping my grammar and vocabulary a bit, I came back to it, and…still found volume one to be above my level. But volume two, I found much easier than volume one. Volumes three and four as well. Some chapters are very difficult (those oriented around the adults having a conversation), and others are extremely easy.
If you liked the premise/characters to Yotsuba, definitely don’t hesitate to give it another chance when you feel you’ve made progress through other methods. But if the story didn’t interest you, there’s no harm in shelving it indefinitely and finding other material.
As for the absolute beginner book club, it can be hit or miss on the material that comes up. The subject matter of the current book, 「結婚しても恋してる」 feels higher level than prior comics in the club to me, but I actually find it easier than the puns in 「しろくまカフェ」 and baby talk in 「チーズスイートホーム」 were. Be sure not to be discouraged!
