How does one get better at a job like teaching? Over time and through a bunch of struggle it seems.

Anne Will talks with Caroline von St. Ange about children and school and the general German situation. And I listen. I complain about wrongs and I look myself deep in the eyes and realize, that I am not doing that great of a job quite often. Instead I complain about the kids and the situation. I could instead prepare better. Or read and learn to then be able to prepare better. I used to have much more drive to try and do things in the classroom. Now I feel spent.
