Dear Sabine, thank you once more for your elaborate comment! You put it beautifully and right on point. Now that you sum it up once more, I can totally see how similar they seem to be. If you are interested in Adler I can really recommend the book “The Courage To Be Disliked: How to free yourself, change your life and achieve real happiness” by Ichiro Kishimi and Fumitake Koga. I absolutely loved it and they manage to bring Adler's theories across in such an engaging form that it's a truly fun read!
It feels quite silly to self-promote but just in case that would be something you're interested in: I make Youtube videos about Adler. They might totally not be your thing but in case that is of any interest, here is a link to a playlist of all Adler-themed videos I made so far: https://www.youtube.com/playlist?list=PLKsPkuT_Mz71QunpRJo5KecM8msEHeoPe
Thanks again for this lovely exchange. Best wishes, Sabine!
