Yes, I am german. Did you watch my video? Because imo every german recognizes an other german speaking english instantly.
The problem is, that you can not hold your productivity at 110%. It is more like a sinus-function swinging up and down. Even if the focus is set and you have your goals in sight does not mean you will succeed easily without failing here and there. But overcoming failure is important and unavoidable on the road to success.
But there are still many things making it harder for us to achieve our goals, but are easily avoidable
