when i think of living a nice comfortable life, not even mega million lotto winner super baller shyt, just comfortable, you need a 100k/yr salary, more if we're being specific to the bay area where i live and more if you have a family. $900k - if you're using the money, is 8-11 years of comfortable living - that's not life changing IMO.
like i said, it's a good chunk to sit on for retirement, maybe take a vacay and buy a new car,
but that's not "no longer need to work money". that would pay my school loans and current mortgage. i'd be back at the office the next week like clockwork.
