1. What do you believe about yourself now that you did not believe before?
You can complete this whole guide without describing what happened. Start with the belief, not the event.
2. What do you believe about other people?
That they leave. That they cannot be told. That they will not help if asked. Write the rule as it actually operates.
3. Where has that belief been accurate, and where has it overreached?
It formed on real evidence. The only question is whether it is still sized correctly for your current life.
4. Where is one small place you could test it?
Small enough that being wrong would not cost much. Naming it is enough for today.
