I'm currently reading Atomic Habits by James Clear. Genre is non fiction... productivity? self help?
Anyways, I kind of like his ideas so far although some of them do sound like there's a huge survivorship bias going on. There's a bunch of "if this totally real person I met at some point in my life can do in, so can you!" which I'm not too on board with, but the general idea of starting a new habit on your terms is so far pretty enjoyable.
