I'm Not Good Enough - Is That a Negative Belief?

If what you wish you believed about yourself was that i am good enough, i wonder if there's a negative belief in there. Maybe they just didn't feel safe enough or comfortable enough to identify the narrative belief of i'm not good enough. Or maybe they're a really logical, analytical i and because they're shame yet, it seems like an irrational response. But even those of us that are really cognitive, we have our irrational responses.
