Hang in there, Adam. I’m in the similar boat as you. I’m 51, looking to retire @55 when my son goes to college (his tuition is already saved in separate 529 account). @4% withdraw rate, we have enough assets to generate passive incomes of $250K+, and our annual living expense is <$100K. Neither me or wife have pension or medical coverage, but we do have 401K and some prior HSA savings.
