Jens Corssen, born in Berlin on 30 April 1942, is a qualified psychologist, behavioural therapist, bestseller author, and one of Germany's leading experts in personal development. As early as 1971, he opened one of the first behavioural therapy practices in Germany.

For over 50 years, he has been helping individuals, leaders, and top athletes develop mental strength, self-responsibility, and inner clarity. His work led to the creation of the „Self-Developer®“ method, which he teaches in seminars, coaching sessions, and books.

In his successful work „The Self-Developer,“ he demonstrates how self-leadership and conscious action can lead to greater life satisfaction, serenity, and personal success.
