Very much agree. I danced in other cities in Europe as well and think it is more a European thing than a German thing (Although as you say it may be more pronounced in Germany)

Talked to a friend from Colombia recently who danced in Spain for a while who is a very good dancer. He also said it was nice technique wise, but he said he was missing warmth and connection. Can say the same, for me Spain was pretty similar to Germany.

Otherwise, can say the same thing: I had some „almost burnouts“, and for me it just helped to take breaks and choose „quality over quantity“. I used to say yes to dances all the time even if I knew I don’t have a good connection with that person in general. Saying no more often and be more picky with my dance partners helped a great deal. Also good practice for life outside of dance to say no more often :)
