Brilliant. Failure is the best teacher out there, and should probably be a compliment. You either succeed or you learn.
But this paragraph was a mindfuck!
If you combine all of the knowledge the entire human race has acquired through out all of human history, it is small when compared to what we do not know. Most of what we do not know is made up of thing we do not know that we do not know, things that exist outside of our awareness. To give you an example, if I were to tell you that I am thinking of a word, you know I am thinking of a word, but you cannot know what that word is. Before I told you that I was thinking of a word, you were not aware that I was thinking of a word. Either way you do not know the word I am thinking of. Before I told you that I was thinking of a word, you did not know that you did not know, and when I made you aware of the fact that I was thinking of a word, you knew what you did not know.
