As an Italian living in Germany, and as a lover of the German language, I think this is not a good list. It reads like it was put together to fit the author's approach to coaching. Entwicklung, indeed, is the best example of this. It is exactly the same in English.

What's really fun about German: as a non native you can get to a point where you create involuntary neologisms by putting together words you already know. Surprisingly, Germans find it mostly funny and tend to understand well what you mean, suggesting that there's an underlying plasticity to this language, if you're mutig enough to play with it and its admittedly strict Grenzen. I just cant's wrap my head around the rule of writing every substantive with a capital letter though, which I interpret as an annoying need to always circumstantiate a purported objectivity of the perceived reality.

With some friends we started coming up with these neologisms on purpose. My favorite one is "Sonnenschuld" or "Wetterschuld", which is that feeling you get in Berlin when you have to work during the summer while the sun is shining outside. You know you're doing the right thing, but at the same time you know you're wasting a precious opportunity to enjoy a rather seldom occurrence.
