James Blake - I only Know (What I know Now)

I only know what I know.
I tried to figure out things beyond word, but It was quite miserable.
What I know and have learned from outside has built up What I am.
The eyes looking at me tell something in unspoken way, so I just guess and find some hint.
So I can't explain and be sure that I know.
But I want to say I felt it.
Sometime, I'd like to be driven by my feeling.
