Last week in Berlin was not the best of weeks I had.
I felt tired, not able to learn any more, detached from my inner self.
While the other went out to the musical after our course I stayed in the hotel and took a big bag of sleep.
I now got the numbers. Just 20 % made it in Hannover and nearly all of our course made it in Cologne.
There is not much you can do against it.
It still makes me angry.
