I've been tracking net worth on a quarterly basis since 2003 and I include everything but (other) personal possessions. I include the house, the cars, investment properties, vested stock options, deferred compensation, etc. With that, I fare well compared to Financial Samurai's aggressive scenario.
Over the past 3 years, I've also been focused on generating passive income (e.g. dividends, interest, and rental income) and I calculate % of quarterly and trailing 12 month spend covered by passive income, while deferring all of my W-2 compensation, to experiment on how I react to having $0 paycheck. I found this to be a good experiment to prepare mentally for when I finally pull the trigger.
I think I'm a money nerd.
