Looking for this Red Book about Finance

Hi, I'm looking for the title of the red book about finance, it was distributed and published in Germany.

It's about advanced money handling, psychology of wealth, behavioral discipline, long-term success systems, delayed gratification, capital growth, mindset upgrade, and productivity loops. It goes deeper in behavioral finance, strategic growth frameworks, and decision-making psychology.

Someone provided all these descriptions and I became curious about it. But, the Title of the book and the author was not stated and I could no longer find his post. I did my research but all it says is about the "Psychology of Money by Morgan" and I'm 100% sure this was not the book since the poster also stated that it's not available on online shopping platforms.

Another keynote: He said it's used by private finance seminars in Europe and is published by a small publisher in Germany. The author was a behavioral finance lecturer.
