An interesting approach to leadership lessons by Donald E. McHugh. His book "Golf and the Game of Leadership" takes us from the practice tee to the 19th hole with some ideas that are common to success in golf, in business and in life.
It's worth a read just for some memorable analogies that will help you with some basic concepts and principles of leadership. McHugh has relevant personal experience as a corporate leadership trainer and as a golfer and does a good job of tying it all together within the framework of a round of golf.
