I kept track of all my personal expenses in ledger for I think 4 years. And then I had twins (plus a 2 year old) and my free time to keep it up to date went out the window.
I learned a heck of a lot about our spending habits during that time though. Super useful and nice that I could look back on cumulative effects of things over time and mix and match the queries different ways to answer different questions.
One of the main things I learned is that cars are really expensive. I brought up the numbers one time to some co-workers and they all insisted they spent nothing near that on their cars, even though I lived closest to the office and had the oldest car in the group.
