Eleven Rings: The Soul of Success by Phil Jackson and Hugh Delehanty:
The mistake that championship teams often make is to try to repeat their winning formula. But that rarely works because by the time the next season starts, your opponents have studied all the videos and figured out how to counter every move you made. The key to sustained success is to keep growing as a team. Winning is about moving into the unknown and creating something new. Remember that scene in the first Indiana Jones movie when someone asks Indy what he’s going to do next, and he replies, “I don’t know, I’m making it up as we go along.” That’s how I view leadership. It’s an act of controlled improvisation, a Thelonious Monk finger exercise, from one moment to the next.
