David Beats Goliath is the story of one man's quest for reaching the top of his chosen profession, but it's also much more. Stefan Langer shares his very personal spiritual journey that changed him from a disillusioned guy with a negative outlook on life who needed to be drunk to have a good time to the goal-oriented, joyful, positive person he is today. Drawing on the wisdom and insights of great teachers such as Joe Vitale, Rhonda Byrne, Anthony Robbins, and Andreas Winter, Stefan Langer's practical and personal approach shows you how to move your life step by step onto a brighter, happier, and more fulfilling path.
