As a self-developer to private and professional success. 4 CDs

Jens Corssen summarizes his many years of experience in successful self-management in this CD collection in an informative, vivid, and humorous way. His insightful findings and stories reflect a variety of thought and behavior mechanisms. His self-developer, equipped with the four tools of self-awareness, self-responsibility, self-confidence, and self-overcoming, has realized that he lives more successfully and happily when he stops trying to develop others. Therefore, he starts with himself to initiate the necessary changes in his thinking and behavior.
