Acht Schritte zum Glück: Mit Achtsamkeit auf dem Pfad des Buddha

I'm curious whether these steps are based on personal practice, traditional teachings, or a mix of both. What inspired the selection and order of these steps?

The steps sound so simple in theory, but applying them consistently in a busy life can be tough. How have others integrated these practices into everyday routines?

The book emphasizes mindfulness and meditation—were there other areas the author considered including, but ultimately left out? I'm interested in the guiding philosophy behind the choices.
