YPSI Trainer License - The recommended literature

This literature is used for the preparation and follow-up of the seminars of the YPSI Trainer Certification .

It is neither a requirement nor an obligation. First and foremost, of course, we recommend all of Wolfgang's books and e-books as a supplement to the content of the YPSI modules.

In addition, there are many very good books by other authors that can supplement the content of the YPSI modules. A selection of the biggest highlights follows.

The lists are arranged hierarchically for each module, ie if you only order one book, you should order the first book in the list for the respective seminar, if you only order two books, you should order the first two books in the list for the respective seminar.
