These CDs teach you how to live a happier - and therefore longer and more successful - life.  Happiness is the key to emuna, since you can tell someone with true emuna by the joy that permeates their being.  Even more, happiness is crucial for self-composure and success in all areas of life.  This set is a fraction of the cost of a single appointment with a psychologist, a 30 day supply of Zoloft, and the like.  Even more, instead of masking the sadness, these CDs give you the keys to banish the dark cloud from your life and live with true, lasting happiness.  It's an investment you won't regret that will save you loads down the line.
