I need, I want, I believe, I expect, I deserve
The My Big TOE glossary gives fear a definition that is one word long in its essential part: fear is about self. Love is about other. Everything else follows from which of those a thing is about.
It then does something unusually practical. Fear, it says, is creatively expressed as ego, belief and expectation — and it expresses itself in terms of value to itself, in a phrasebook you can actually listen for: I need, I want, I believe, I expect, I deserve.
That is a detector you can run on your own speech. Not because those phrases are forbidden, but because each one marks a place where something is being claimed on your own behalf. Notice how often they show up in a description of a conflict, and who they are always about.
The same entry offers five roots that most individual fears trace back to: not being good enough, pain, the unknown, not being in control, and death. Worth knowing, worth not over-using — the roots are a map, and a map is not the territory.
The app does a little of this for you. When you write in the journal it quietly points at those five phrases if they turn up. It is noticing, not correction.
The five roots appear on the official site rather than in Campbell's own voice, so the app presents them as the framework's rather than as his.
