I'll start:
* Re-reading Words of Radiance by Brandon Sanderson. I had forgotten the story leading up to Rhythm of War. I had forgotten how fun Sanderson's world is.
* Just finishing up Project Hail Mary by Andy Weir. Great book. I didn't read Artemis, but The Martian was awesome.
* Grit by Angela Duckworth. Really speaks to me and has me re-examining my own loss of focus and tenacity in pursuits, and my expectations of how long achievement takes.
I'll probably pick a few more once I'm done with these.
If I could give it a short description, it's pretty much the modern equivalent of The Prince and i highly reccomend it to everyone!
