Atomic Habits is a great read, and if you’re in this season of wanting to change some stuff about your day-to-day life, I think it’s worth prioritizing. A lot of contemporary discussion regarding habit forming (and the many ways that it can show up and apply in niches) really seem to draw conceptually from and apply within the niche what’s outlined within the book. I think a lot of it just makes sense, since habit forming really just boils down to “just continue to do the thing”, but it goes into some great detail on how you can build support systems for yourself that make sticking with your new habits feel easy & effortless.
For example, as I mentioned prior, my lunch break reading is dependent on me packing a lunch. I’ve made it easy to read by ensuring I have the time to both eat, and have enough time to burn through a few pages. Reading alone has always seemed conceptually simple to execute, but I always struggled to do it. Ensuring I have the time to do it in a pocket in the middle of the day by packing a lunch has made it much easier to stick with it. May sound silly to some, but it’s what’s worked for me so far.
If you’re interested in reading some more life improvement books, consider making manga the reward for reading other things you want to accomplish. Something as simple as setting a 10 minute timer, read the one book, then afterwords give yourself an out to swap with manga for the rest of the time could be a helpful way to start getting the ball rolling. 
Epos has some similar discussions in a handful of videos too that touch conceptually similiar some of the ideas in the book with the videos on session gaming (can’t remember exactly which video), seasonality play, & reducing the friction, if I’m recalling their contents correctly.
