Some of the best anecdotes from In War and Peace is by the second-term, Eisenhower had basically delegated the government to his cabinet because he was so over it. The entire Suez Canal Crisis and installation of the Shah in Iran was a Dulles' joint that Eisenhower barely knew anything about.
The biography by Jean Edward Smith is exceptional.
That and the fact that he decided that if he didn't run on the Republican side, he feared that the party itself would disintegrate. There is a great write up in the Biography Eisenhower in War and Peace by Jean Edward Smith about it.
I reread Atomic Habits by James Clear back in the fall and that book never fails to give me some clarity. But as for first-time reads, I think it's a tie between two military biographies:
Eisenhower in War and Peace by Jean Edward Smith. We're all familiar with the Eisenhower matrix but the full story of Ike's life gives a full picture of a person in complete control of his own will (with a few unfortunate exceptions). That trait and his leadership while President are inspiring.
Call Sign Chaos: Learning to Lead by Jim Mattis and Bing West. The autobiography of Jim "Mad Dog" Mattis, former US Marine general and Trump's former Secretary of Defense (although don't hold that against Mattis, as he's since been quite public about his disagreements with Trump). This man is simply a complete badass, a "warrior monk" whose intellect matches his professional focus. Check out his reading list. I learned from this book that (1) productivity means nothing if you don't focus on the people you are leading or serving, and (2) to do this well you have to read.... a lot, and widely.
Can't find one online, but this book has quite a bit about it, and is very well researched and noted.
I'm reading a thick biography of Eisenhower by Jean Smith called <em>Eisenhower In War and Peace</em>. Very thorough, challenging, and stimulating thus far!
