I think everyone is a teacher to someone else. On the other hand, everyone is someone else's disciple. That is, in social life, students have no limits on age or level of education. Because everyone is required by conditions to always learn in living their lives. Furthermore, every soul is a teacher for every body, this means that every person is both a teacher and a student for himself.

In my opinion, modern education is now more primitive than existing education. Isn't modern today primitive for tomorrow?.

For me there is no level of education. Education is just education. So learn anywhere, anytime and to anyone. Do not be afraid, because knowledge will never run out.
