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, new home, less control over kids expenses, etc). DO NOT RECOMMEND!
Also note, I do not include the $500,000 we saved (in 529 funds) for college, 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 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.
