I try to read two books in parallel: one fiction (sci-fi or fantasy, usually) and one non-fiction (history, philosophy, economics, or psychology).

I’ve found that this approach keeps things fresh, and allows me “cooldown” and let my imagination flow periodically. I used to read even more books in parallel (3-5), but 2 books has been the sweet spot for me.

Right now, I’m switching between “Oathbringer” (Stormlight Archive series) and “Capital in the 21st Century”.

I also used to listen to a lot of audiobooks and I’m trying to get back into that.
