I read a lot. Mostly SF and fantasy. Something which has been 'taking over' a lot of online communities about those genres (probably also in other genres) in recent years is the concept of #reading challenges.
I finally figured out something which bothers me about them. They turn reading specific #books into something which you do because you're extrinsically motivated!
For me, reading has always been something I do because I'm intrinsically motivated, but I recently caught myself thinking far too much on how to make books fit into such challenges, including picking up books which I didn't actually feel like.
I'm all in favor of people reading more - and more broadly - than they would've done without these challenges, but I already was reading exactly as much as I want to!
Going forward, I'm going to stay far away from the inherent reward-loop from these challenges, and just read what I feel like, when I feel like it. Much healthier for my brain, which is far too susceptible to such things.
