A wonderful book by the ISKON group of organizations. Based on the life of ISKON's founder from the POV of his leadership, contextual to his spirituality.
If you're not a religious or spiritual person, you might need to be more accommodative towards the religious and 'be-in-service-to-the-lord' perspectives that the book is based on.
Despite that, it's a worthwhile exploration to read this, since parallels and analogs can be drawn even then.
