What helped me make my emergency fund (tomato, toMAHto) possible long term (it’s got to be long term and perpetual or it’s not going to be there when you need it) was to program x amount into a separate fund. Every month. Automatically. No thinking. I don’t even look at except once a quarter when I update interest earned in Quicken. But that fund has been through several career changes, it’s on its second marriage, it helped pay off a mortgage and a father-in-law’s end of life bills. And any time I get sick of my job, I can walk away. I haven’t, but just knowing I can gets me through awful days.
