The right question at the right time can change the course of a life, can still a turbulent mind, or heal an angry heart. While every situation can generate its own, there are twelve questions, I think, that deserve to be asked not just once but many times over the course of a lifetime, some even many times over the course of the day. I have gathered them from some of the wisest philosophers, most incisive thinkers, greatest leaders and most awesome badasses that ever lived. I’m not saying I know the answer to any of them, but I can say there is value in letting them challenge you. If you let them. If you let them do their work on you—and let them change you.
