Notwithstanding Jim's AWESOME clip, I think you're at the point now @didomachiatto where you need to take a step back and see how simple it is by looking at examples.
Can you see how Obi-Wan is "You" in Star Wars (1977) while Luke is "I"?
Ditto with Morpheus and Neo in the Matrix, Westley and Buttercup in The Princess Bride, etc. etc. with whatever stories you feel you could grasp best.
If the terms "You" and "I" don't jive, then use impact/influence and personal struggle.
I agree with you 100% Greg, however just wanted to point out that you could (and probably this would just happen naturally) still show IC story points in a scene from the IC's POV. So while showing thoughts is a storytelling technique, the conflicts shown by thoughts might point at items like IC Issue or Problem or Focus etc. Which are part of the structure.
