Self-Improvement
Duration: 30 minutes
First broadcast: Thursday 27 February 2014
Self-improvement: If you want to look better, feel better, perform better, there's no shortage of help available. Whether it's cosmetic surgery for the perfect body, fitness programmes to boost self-esteem, or self-help books to improve the mind, there's plenty of choice. But do they promise the world and fail to deliver - or give you the strength to achieve the personal growth you desire? Evan Davis and guests discuss the industry of making your life better.
Guests:
Jon Congdon, President and Co-Founder, Beachbody.com
Carole Tonkinson, Publisher, Harper NonFiction
John Ryan, Founder and Chairman, Make Yourself Amazing
