I once had a teacher, not a teacher that only teaches what was in the books we used for school, but also a teacher in a more bigger way of the word. He teached me that you can only teach someone something by try to give them there own vision. When other teachers told us we should make our homework, he told us we could, because we wanted to. You didn’t have to. If you didn’t want it was also fine. But why were you at school again?
If you want to teach, let go of the idea of doing so, just act. You are what you teach.
