People are damn inspiring on here! So, for posterity I did my best estimate of NW since discovering MMM in 2015. The fact that I can actually go back and reliably track this information is itself a testament to the good ideas from MMM.
FWIW, I've been doing this as a recently (2014) divorced dad of two who had the kinds of expenses that no one preparing for FIRE would advise (child support, outfitting a new home, less control over kids expenses, etc). DO NOT RECOMMEND!
Also note, I do not include the >$500,000 I have in 529 funds since it's the kids money and we are now withdrawing from it for college tuition. Lastly, also note that I did get re-married in 2018 and that she brought $40k (that's it...her first husband bankrupted them!).
July 2016: $247,000
July 2017: $319,000
July 2018: $356,000
July 2019: $432,000
July 2020: $477,000?
Now that divorce-based expenses end in July 2020 I hope to get to $1m by 2025, or sooner.
