Extreme Ownership: How U.S. Navy SEALs Lead and Win
Jocko Willink, Leif Babin
"Everything is your fault, the end." One of the single greatest books on leadership accountability. Probably top of my list. Highly recommend listening; read on audible by the authors.
A masterclass on OKRs and goal setting, following Bill Campbell's methods across the world's most valuable companies. A must read for product managers.
