$330k liquid split over checking and savings. 400k in "retirement accounts" - bearing in mind that 18k (current max 401k contribution in 2015, so this would be higher than years ago) times 8 years (assuming starting work at age 21) would be ~144K in contributions, so pretty damned good returns there...
then on top of that 8.4 Million in illiquid assets?
I seriously feel sometimes that there's things that have gone WAY over my head despite living around here for 8+ years and working in tech.
