The only true wisdom is in knowing you know nothing.

More I teach, more I learn, then, I realise a fact that how much I do not know about what I am teaching and what I am doing.
Experience provides more questions, new answer double the question.
I really often wonder how much I really understand what I am trying to communicate with the students.

The only true wisdom is in knowing you know nothing. This is a quote of famous philosopher Socrtes.
I do agree with him, however, it does not really help the situation. This is a very deep true wisdom, but not practical. If, not practical, that means useless.
I think I realise how much I do not know about what I am teaching every time I teach or take class.
So, what can I do?
