I am teacher

In a sense that I am your teacher.
Lets try to teach you.
Class already began when you started reading.
Today I will teach about history.
A man who knows what I know once said,
To be or not to be.
I would rather excel in the knowledge of the highest secret of philosophy rather than in arms.
The true wisdom of the knowledge, is that you know nothing.
How about...
I am the way, I am the truth, I am the life?
Or
Man who created my native tongue.
Great king saejong...
