Pretty good. Mildly informative and entertaining, but came off a bit weak after my recent reading of Stumbling on Happiness. This book provides some insights as to why we do some things that make sense, but isn’t quite as deep or as engaging as the other. The anecdotes in Sway are pretty good (especially the airplane one, and the $20 auction, although it’s the third time I’ve encountered that one in recent history, so it’s lost its punch), and it’s a short read, so I’d recommend it, but it’s not an absolute must-read.
