I liked the book Extreme Ownership: How U.S. Navy SEALs Lead and Win: 9781250067050: Willink, Jocko, Babin, Leif: Books.
The main idea I took out of it? You are responsible for the success of any task, any project, any life. Even if at times external factors can interfere, you are 100% responsible for the success in your life.
Quite a nice idea!
