Who has a detailed file on their projects?

I started out with a very detailed set of Pics and receipts... Have the pics but quit keeping all but the higher dollar item receipts in a binder. Quit adding it up when I saw I was close to what I thought I was going to spend total and am not even close to being done...Don't want to know and Wife quit asking what things cost. I still take pics but it's more just for my memory than anything else. I have kinda lost interest in the car but it gives me something to do.
