Dan McGinn is the author of  Psyched Up: How the Science of Mental Preparation Can Help You Succeed. The book focuses on the topic of science and mental preparation. Stress can effect everybody and people in sales are certainly not immune. Unlike athletes, sales leaders often do little mental preparation before big meetings or events but there is a lot of research suggesting that people who engage in certain behaviors before stressful activities or high-stakes performances perform better. The book highlights such activities as listening to motivational songs, having a routine, or performing a certain set of actions as great ways to get psyched up.
