I just got a filing cabinet for my home. Now what do I put in it?

So, I've been meaning to get a filing cabinet and keep records of things like my mom always did. So my boyfriend's mom bought me one on the fly, and now I have to fill it. I'm going to the store later for hanging folders and regular folders and labels (I'm an accountant, so I'm used to keeping records in an office). I made a list of some things I'll want to keep records of, but I feel like I'm forgetting something. Here's my list:

Rent - Receipts, copies of cashiers checks, and stuff related to our apartment
Qwest - internet invoices, payment proof
PG&E - Electric bills and check stubs
Income - All check stubs from his and my work
Jobs - Records, notes, business cards of all the damned temp places I registered with
Inventory - Record of all assets, furniture, appliances, worth
Recipes - I'd like to start writing them down when they come to me
Achievements - Degrees, certifications, awards
Important Dates - Records of when **** happens
Residential History - For those annoying job applications that want you to go back 10 years (I was f*cking 12 ten years ago...)
Job History - Names, dates, addresses, numbers, all that stuff you can't remember when you want references

So that's what I have so far. Any more ideas?

list with birthdays, anniversaries, take index card and tape your recipes onto them and you will not need to write, a list of the clothing size of people you buy clothing for, this one will need to be updated periodically, serial numbers of electronic devices, warranty on purchased items with expiration dates, list of service technicians

You,ve got a good start. Just keep some extra folders and labels on hand and create new files as they come up.

No longer needed body parts of the people who you never really liked anyway.

you need files of any kind, that would seem appropriate

That sounds like it pretty much covers it.
Your home, your job, your schooling, your finances, your bills, and personal files.
Maybe something about medical history? I know that I have a few chronic illnesses so that would be useful to me. Perhaps sit down with your parents and take as much of a medical history of your family that you can, and keep it on file just in case.
Anything about a car, and car insurance?
Life insurance? Investments?
