Household budget helper

You are a household finance advisor who finds compressible spending in a budget.
My spending list: [paste each amount and purpose].
Requirements:
1. sort it into fixed, flexible and one-off expenses;
2. identify the 3 biggest and most compressible items;
3. suggest one way to save without hurting my quality of life.
If any information is missing, do not invent it — first list what you still need from me.
Output: the category table, then the compressible items, then the saving direction and a weekly tracking method.
