Just finished Stolen Focus, by Johann Hari. It's an excellent read.
It covers why attention spans have degraded over the decades, a huge chunk of which is due to corporate social media. It covers a lot of ground, includes a lot of research, and has an excellent systemic analysis (instead of the usual individualistic focus of self-help books).
If you care about your mental health, or global geopolitics, or climate change, I'd strongly recommend giving it a read.
@naught101 this was an excellent book that I just finished too.
@craige I took a lot of margin notes! Got a few that I might submit as mastodon issues/discussions, even. Lots of good thought provocation.
@naught101 that's a great idea but dangerously close to a book club 
I listened to the book driving up from Brisbane recently and took copiuos amounts of mental notes that are now all forgotten, so I think sharing your notes would be great.
@craige Actually extracting my notes from the margins might take a while
