Das Prinzip des geistigen Erfolgs : der Schlüssel zum Power-Programm (Perfect Paperback)

The book feels like a quick pep talk rather than a deep dive. I'm curious if this format was a deliberate choice to make the advice more accessible or if it evolved from his teaching style.

Some tips felt almost too straightforward, but I wonder if that's the point — to cut through the noise. How did others connect with the practical suggestions?

I've read similar books, but this one felt more like a quick reminder than a comprehensive strategy. Do these tips stick with people long-term?
