How to use
先把最坏情况的月供算出来，再决定签不签字。
Try tweaking it
- Ask for a checklist and timeline, marking which parts need a professional.
- Replace "what should I do" with "which three things first, and when".
What you should get
- An ordered action list with deadlines
- What must be confirmed with a professional or official channel
Common mistakes
- Using it as the doctor or lawyer and acting on the answer directly.
- Taking a single conclusion without asking about preconditions or real costs.
How to check the output
- It gives an order of steps and a decision deadline.
- It flags what must be confirmed with a doctor, lawyer or official channel.
Where it works
- Good for: turning everyday decisions into checklists and timelines, flagging what needs a professional.
- Watch out: health, insurance and legal output is reference only — confirm with a doctor, broker or lawyer.
