A friend of mine told me about No Easy Day by Mark Owen way before it got its press notoriety. The story was written by a Navy SEAL who participated in many historic missions, such as saving the hostages from the Somali pirates and the raid on Osama bin Laden. I was interested in checking it out for the details of how SEALs train and organize and less so for the political details surrounding the UBL raid. Luckily, this was how the author felt as well, as his story was direct, fact-based, and with practically no political or emotional rhetoric.
I enjoyed learning about how SEALs train, how they organize their own gear, and how they manage their attitude in the face of grueling hours and immense physical burden. The book was inspiring and gave me some good advice about perseverance, like just focusing on getting to the next meal when enduring difficult work or training. Despite the author's incredibly significant accomplishments, he remained humble throughout the entire book, and several times, he even said that when you start celebrating your own hype, that's when you're in for trouble. I like that attitude of focusing on reality and getting stuff done. I was also impressed with his immense dedication to his work and his love of it, and how that drove him to make difficult decisions for the benefit of his work. That was an example of the good/right definition of selfishness.
