I noticed on a recent visit to the bookstore that books on golf and business are remarkably similar.
Catchy titles: "The six rules for success", "The only book you'll ever need to need to read" , "Learn from the pros", etc. .... And the selections are similar; mastering techniques, applying psychology, or success stories from the past.
But in business and in golf, studying the subject and knowing the principles for success are not enough. You have to practice and get better by doing it.
Learning from experience and not just experiencing the experience will make all the difference.
