Yeah I know what you mean,
I just don't feel i'm at the level yet to be selling my services..
I can read CSS3, and HTML 5 and know what it does, but when it comes to writing code from scratch I have writers block.
I know what you're thinking, just use the programs do the work for you, but I want to write from scratch. I feel that if you invest enough time and energy into your designs and build a rep for having some bad ass websites you can accomplish anything.
With the change to responsive design, everything that i've learned has basically been altered once again, and now I have to change with the tide.
But i'm not at that level yet, I just read code right now, not write code.
