You should get out of your zone of comfort and write in German! :)
We don't have much powers to change the other people around us. Our strongest power is to change and develop ourselves and lead the others by example ;)
So sharpen your written German and start using it! :P
What you are talking about is not possible 🙂 Anyway, mastering foreign languages wasn't this post's topic.
As for changing myself, right now I doubt that would help in any way.
