This may evolve over time, but for now I will be regularly sharing some of my favorite bits and pieces of my personal finance spreadsheet.
Exhibit A: Spending

I've been tracking my spending for several years and it has seemed to stabalize around $17k. In recent years, more than half of my spending has gone towards rent. If I could eliminate that category, or significantly reduce it, then FI would be right around the corner. Who knows, maybe I'll give van/rv life a try, or purchase/build a simple dwelling in a low cost area. Time will tell.
Exhibit B: Saving

I've only been tracking this for a few years. I count my pension contributions because they are refundable when I quit. This particular pension is wonderful if you spend 30+ years contributing to it, otherwise it's pretty awful. Once I quit, I plan to cash this out and invest it on my own.
Exhibit C: Net Worth

Significant progress in the last few years!
Exhibit D: FI Progress

Closing the distance!
Exhibit E: Investments

This is extremely boring, I know. Very Boglehead-ish. Gotta say, I love the 457(b) and refundable pension! I can withdrawal the 457(b) penalty free at any age, as soon as I leave my job. If you haven't guessed yet, I'm a government employee. The refundable pension is also great, and since I'm covered by a pension, I'm not subject to Social Security withholdings. Yes, this will reduce my SS benefit in old age, so it's a trade off, but I'm starting to think government work is really compatible with ERE/FIRE.
Exhibit F: Lifetime Earnings

I like seeing the ratio creep upwards. I wonder if my net worth will ever exceed my lifetime gross earned income. Maybe!
