The issues that "Always, Never, Could, Should and Can't" are big ticket items. They may exist in the spectrum of a person's behavior, but to that person those behaviors may not be big ticket. To them, your "I" as their "You" may Always just be stuck on these expectations of their "I".
When we add time to space in the equation of our lives, the implicit memory tends to eliminate Maybe. That's it's job after all, to eliminate not knowing. So it scours it's stronghold of related experiences and eliminates all but the best fit, inserting it so we "know" what our "you"s are like and likely to do. This equation produces the momentum of the motion of our lives as they are filled with the perception of people, places, and things.
When you add time, to your I, You, We, They, and This with Always, Never, Should, Could, and Can't you are basing your present on your past to produce your future, all because your implicit memory wants to save you the trouble of perceiving.
Look at it this way:
I - You - We - They - This
Always - Never - Should - Could - Can't
Yeah, you see, these are some of the infamous first and last words in arguments, misunderstandings, and criticism of oneself. When you hear them in any combination, little blue bunnies are propagating like rabbits.
Practice this: Instead of filling in the blank of what some "you"-"never" does, or something "they"-"should" do; just repeat these ten words like a mantra: "I, you, we, they, this; always, never, should, could, can't. Nevermind." Memorize and start repeating this in your mundane moments until you implicitly know the rhythm and the words.
When you notice any of these words coming up in any combination, repeat the Nevermind mantra until your implicit little helper stops offering reasons why and what to do and the rest of its collection. Then, being lucid in your dream of life, see what you don't see....Nevermind.
