No, don't tell your boss to shove it...at least not out loud. But in your head accept that from this day on you're a free agent whose number one workplace priority is your personal bottom line.
You should be as conscious of spending as you are of saving. Credit should be a rarely used tool for those few times (buying homes and cars) when paying cash is impossible.
Your work life should be a journey up and down hills, rather than a climb up a sheer cliff that ends with a jump into the abyss.
It sounds terrifying, the one intolerable outcome to your financial life. And yet, in truth, dying broke might be your best option for a life without fear: fear of failure and privation now, fear of impoverishment in the long run.
