Look at me, I can't begin to describe how well I know the theory. I could write a book on the theory and win awards on my accuracy. I could color code the theory, put neat little tags around it and write out a table of contents. I could do all this with one eye shut, and an arm tied around my back.
Point is, I'm tired of listening to the theory. I know it all by heart.
It's the practice I'm useless at.
