Note the part about emphasizing working on either your left or right hand separately; then later together.

Also, in my experience one of the biggest physical-mechanical problems people have is they are too tense (their fingers, hands, even arms and back). They are squeezing the strings, neck and, or pick SO HARD that there is no way for their fingers and hands to physically move any faster. Hence, a "wall" or barrier". So, relax, let the pick glide over the strings, and only fret the notes as hard as necessary in order to cleanly sound the note. Any harder and it's wasted effort that is only slowing you down.
