"Left of Bang" was a good read.
I'd add "Blink" by Malcolm Gladwell, as a good dovetail with LoB. Gladwell dives into how much of information do we really need to make a good decision.
He looks at situations where 1, 2 or 3 seconds was plenty, and under some circumstances - more is detrimental. And he also examines situations where "split second" decisions aren't the most reliable. And when and why they're different.
"Leadership and Training for the Fight" by Paul Howe is also a very good book. It talks about proper ways to lead, but also how to develop and mentor up leadership under you. It touches on mindset, and spends a fair bit of time talking about teaching, and effective instruction. Particularly, how to mentor other instructors in your POI, so it outlives you, and the information doesn't die when you move-on, get reassigned, or retire. For guys who teach within an agency or unit, this is particularly good info to ensure your baby, your POI that you developed and slaved over, outlives your work cycle.
"Extreme Ownership" and "The Dichotomy of Leadership" by Jocko Willink and Leif Babin are also excellent leadership books. The format is well thought out, such that each "lesson" (chapter) is given in 3 sections:
1. Real world example (from their unit's time in Iraq)
2. Stripped down explanation of the extracted concept
3. Application to business (a real world example pulled from their time consulting with civilian businesses and applying thier concepts).
The concepts are simple, but not easy (but that's leadership, period.) But, I like that the lessons learned are laid out and easy to digest (no need to try to extract them from a story, or interpret your own take aways.)
I gave these two books to my wife (Extreme Ownership and Dichotomy) who manages two separate medical office buildings for a large health care company. She has approximately 80 people she supervises between both, and she said those two books changed her managerial life.
Just $0.02 from a nobody who sumtimes reeds books to try to get smarterer.
