Yes, you need to have ideas what may be blocking you. If you do not, don't listen to Side A. Just do Side B.
Try this:
Goal: To improve my guitar playing.
Behavior that may be getting in the way of my goal:
How I feel about my abilities
My internal response to my playing
How I am fingering the strings
--in other words, use your imagination. Come up with statments that work for you. Ambiguity can work when you are not sure.
Listen once for each of the above, or each behavior you put in the list.
