华尔街基金经理Costance Brown，在退休的时候，被同事说服写下一生的职业技能的精华：
Traders have been asking me for more than ten years towrite this book. Being a fund manager, there was no chance I wouldwrite a comprehensive book on the price-projection methods I used orthe research that was developing from the methodology. But times changeand a wise partner of mine asked. "What is your business exit strategygoing to be?" He explained that all the knowledge and wisdom you havegained over the years will be lost if you have no plan to pass it on tothe next generation. It is not enough to come, extract from themarkets, and then hide in a cave with the best gems you have polishedover the years tucked safely away in the deepest partitions of yourmind. What good was the journey if someone does not pick up the Hag andcontinue to move it forward?
