Probably about the same way I do things now, TBH. Direct deposit is a requirement, and it’s incredibly easy to set up automatic bill drafts. The paycheck gets automatically divided out to various accounts, savings, investment, etc., BUT…
For YEARS now I’ve been bartering for just about anything you can think of. Once bartered a gun I didn’t like and it’s corresponding ammo in lieu of a down payment on a new wakeboat (he gave me roughly 3-4x its worth). Lots of buying and selling under the table, flipped a car I had for a year at $10k over what I paid (thank you pandemic!) and have been stockpiling ‘hard currency’ of various types. If I find exceptional deals in things, I’ll buy it and wait until someone REALLY wants that thing and sell it for more than what I paid, or barter for something I REALLY want (but refuse to pay that kind of money).
You can also barter services. Husband is a killer welder and fabricator and frequently takes goods as payment rather than cash. I have helped to clean homes, babysit kids, make meals for various things.
