Peter Weddle, founder of the International Association of Employment Web Sites (IAEWS), has written a book titled "Work Strong: Your Personal Career Fitness System," in which he applies analogies such as fitness, athleticism and the classic Olympian in order to describe and explore the concept of "career" in the 21st Century. The subject matter couldn't be more relevant in today's economic climate; as many find themselves forced to reinvent their professional lives, Weddle's book explores once unconventional approaches to career that will become more and more the norm in years to come.
